Arabic TH B Ṭ concerns hindering, slowing, and preventing an action. It can describe someone wishing to act but being held back by an obstacle, or someone who slows or fails to continue because of sluggishness, heaviness, or weakness.
The main concern is an obstacle in the way of action. This may be imposed from outside, such as an illness preventing movement, or associated with weak resolve, fear, discouragement, or being occupied with something else.
These causes are not all fixed components of the root’s meaning. Tathbīṭ denotes hindering or slowing action; context establishes how it happens and why someone fails to act.
The root occurs only once in the Qur’an. In Al-Tawbah 9:46, a group fails to accompany the Prophet. The verse first says that genuine intention to depart would have led them to prepare, then states that The God disliked their setting out and held them back.
Quranic Arabic Corpus: sole occurrence, Form II
Al-Tawbah 9:47 clarifies why their participation was undesirable: joining the believers would have increased disorder and corruption rather than benefiting them.
Tathbīṭ here thus means preventing a particular departure, while the surrounding verses explain the reason and value of that restraint.
1. The semantic core in early Arabic
Al-Khalīl ibn Aḥmad says in Kitāb al-ʿAyn:
«ثَبَّطَهُ عَنِ الْأَمْرِ تَثْبِيطًا، إِذَا شَغَلَهُ عَنْهُ»
thabbaṭahu ʿani al-amri tathbīṭan, idhā shaghalahu ʿanhu
He held someone back from an affair or occupied them otherwise, so that they failed to undertake it.
Kitāb al-ʿAyn: diversion and restraint
This definition illustrates an important aspect of the root.
Someone may intend an action, but another occupies them with something different, preventing the first action.
For example, repeatedly distracting someone with secondary matters while they are attempting a duty can constitute tathbīṭ.
Diversion is nevertheless only one way of hindering.
Fear, discouragement, or a practical obstacle can also hold someone back.
Other lexicographers accordingly record a broader field for the family.
Turning someone away from an intended action
In explaining Al-Tawbah 9:46, Al-Zajjāj defines tathbīṭ as:
«رَدُّكَ الْإِنْسَانَ عَنِ الشَّيْءِ يَفْعَلُهُ»
radduka al-insāna ʿani al-shayʾi yafʿaluhu
Turning someone away from something they are doing or undertaking.
The definition foregrounds holding someone back from a direction or action.
A person is pursuing an action, or has it before them, but something causes them to turn back or discontinue it.
This accords with Al-Khalīl’s sense of diversion without being confined to it.
Threats or obstacles can prevent action without introducing another occupation.
The shared meaning is therefore best expressed as preventing progress or action; diversion, slowing, and turning back are ways it can occur.
Slowing and delaying
Lisān al-ʿArab explains thabaṭahu ʿani al-shayʾ through slowing someone, making them wait, or hindering action.
Tathbīṭ here need not mean permanently ending the activity.
Someone may be held back temporarily and later resume their journey.
Illness, for example, may delay travel that is undertaken after recovery.
Alternatively, restraint can prevent action at the necessary time, so that the opportunity is lost.
The root therefore concerns both slowing and failing to proceed.
The sentence determines the delay’s extent and whether nonparticipation is final.
Heaviness and sluggishness
Lexical sources use thabiṭa of someone becoming sluggish, heavy, or slow in action.
Thabiṭ can likewise describe a person or animal whose movement or action is slow and difficult.
Early explanations sometimes connect this with weakness or inability to act effectively.
This use is clearly related to tathbīṭ.
Someone moving sluggishly may be unable to act in time.
Physical heaviness should nevertheless not be made the root’s exclusive core.
A physically strong person can be hesitant and indecisive.
Conversely, someone motivated to act may be prevented by illness or an external obstacle.
Physical ability, inward motivation, and practical opportunity must therefore be distinguished.
The family’s shared core is slowing or hindering action and preventing progress towards an undertaking, whether the obstacle is inward or outward.
2. Forms and varied uses
Thabaṭa and thabiṭa
The Arabic Form I verb is recorded with different uses.
Thabaṭahu can mean holding someone back or preventing movement.
In thabaṭtu al-rajula, the speaker has restrained or delayed another person.
By contrast, thabiṭa can describe someone becoming sluggish, heavy, or slow.
The transitive–intransitive distinction matters here.
In a transitive construction, someone or something causes another to remain behind.
In an intransitive construction, slowness or sluggishness is attributed to the subject.
This does not establish that every slowness is voluntary or every restraint forced.
The cause requires separate examination.
Thabbaṭa and tathbīṭ
Thabbaṭa is Form II.
Its verbal noun is tathbīṭ.
An agent causes someone to refrain from undertaking or continuing an action.
Thabbaṭahu ʿani al-amr, for example, means holding someone back from an affair or slowing and weakening their action.
Some sentences associate tathbīṭ with discouragement and weakening motivation.
The verb does not necessarily mean merely uttering discouraging words, however.
Restraint may occur through circumstances that induce someone to abandon movement or practically stop the action.
Only this verbal form occurs in the Qur’an.
Tathabbaṭa
Tathabbaṭa is Form V.
Lexical sources use it for someone held back from an action or brought to a pause.
Early explanations gloss thabbaṭahu ʿalā al-amri fa-tathabbaṭa as making someone pause at an affair, whereupon they paused.
Form V here can express the resulting state in the person.
It should not always be understood as a deliberate decision to abandon an action.
An external cause may produce the restraint.
Athbaṭa
Arabic also records Form IV athbaṭa.
In athbaṭahu al-maraḍu, illness grips a person so persistently that it scarcely leaves them, restricting normal activity.
Illness is the restraining factor here.
This shows that tathbīṭ and related forms concern more than fear or weak resolve.
The obstacle can be entirely physical and beyond someone’s immediate control.
Failure to act should therefore not be judged moral weakness or dishonesty without examining the cause.
Thabiṭ and thabiṭah / thabṭah
Lexical sources use thabiṭ of someone slow, weak, or sluggish in movement and action.
The feminine thabiṭah is also recorded; some transmissions have thabṭah, with a silent bāʾ.
Lexical sources: morphology and feminine vocalisations
These descriptions alone do not determine moral worth.
Slowness of movement may reflect age, illness, bodily characteristics, or environmental conditions.
By contrast, sluggishness in fulfilling a duty may arise from inattention or lack of resolve.
Physical description must therefore be distinguished from judgment of responsible conduct.
3. A poetic witness and a significant textual variation
Lisān al-ʿArab quotes a hemistich by Labīd ibn Rabīʿah under TH B Ṭ:
«وَهُمُ الْعَشِيرَةُ إِنْ يُثَبِّطْ حَاسِدٌ»
wa-humu al-ʿashīratu in yuthabbiṭ ḥāsidun
Explanatory rendering of the hemistich: “They are the clan, if an envier [seeks their faults].” This isolated hemistich is quoted with its lexical explanation, rather than as a certain text of the complete verse.
As transmitted in Lisān al-ʿArab, Ibn al-Aʿrābī explains this wording as searching for the clan’s faults. Connecting it with deterring others from support is a further contextual explanation and should not replace that lexical report.
Lisān al-ʿArab: yuthabbiṭ and Ibn al-Aʿrābī’s explanation
Labīd’s collected poetry and early commentaries on the Muʿallaqah reveal an important variation.
A widely transmitted version reads:
وَهُمُ الْعَشِيرَةُ أَنْ يُبَطِّئَ حَاسِدٌ
أَوْ أَنْ يَلُومَ مَعَ الْعِدَى لَوَّامُهَا
wa-humu al-ʿashīratu an yubaṭṭiʾa ḥāsidun / aw an yalūma maʿa al-ʿidā lawwāmuhā
An explanatory sense translation is: “They are a united clan, such that an envier does not deter people from supporting them, nor their reproacher join enemies in blaming them.” The negation comes from an understood construction and interpretation; this version contains no explicit negative word.
Here yubaṭṭiʾa derives from B Ṭ ʾ, rather than TH B Ṭ.
Labīd’s Dīwān: yubaṭṭiʾ and second-hemistich variants
Lexical sources and commentaries report further variants; each version must therefore be quoted from its source and assessed under its appropriate root.
This variation is fundamental to studying the root.
Is the verse conclusive evidence for TH B Ṭ?
If Lisān al-ʿArab’s yuthabbiṭ is original, the hemistich attests this root in an envier’s fault-finding; a connection with deterring support requires contextual explanation.
On that interpretation, the envier seeks to deter support by exposing or inventing faults.
Reliable editions of the collected poems and Muʿallaqah commentaries also record yubaṭṭiʾa, however.
One lexicon’s quotation does not establish that Labīd certainly used TH B Ṭ.
The witness helps examine the proximity of the semantic fields, but cannot conclusively establish pre-Qur’anic use of TH B Ṭ itself.
Al-Muḥkam: the yubaṭṭiʾ version
Nor should yubaṭṭiʾa be silently changed to yuthabbiṭa and the altered wording then presented as evidence for the desired root.
What the witness establishes
The verse concerns someone seeking to slow or deter others through disparagement and fault-finding.
This is close to tathbīṭ.
Since the wording is disputed, two matters must nevertheless be distinguished:
First, the independently recorded lexical meaning of tathbīṭ.
Second, the reliability of this particular verse as historical evidence for that root.
The lexical meaning is clear, but the poetic witness alone lacks the certainty needed to reconstruct the word’s history.
This caution avoids constructing an apparently ancient but uncertain foundation.
4. The sole Qur’anic occurrence: Al-Tawbah 9:46
Verse text:
وَلَوْ أَرَادُوا الْخُرُوجَ لَأَعَدُّوا لَهُ عُدَّةً وَلَٰكِنْ كَرِهَ اللَّهُ انْبِعَاثَهُمْ فَثَبَّطَهُمْ وَقِيلَ اقْعُدُوا مَعَ الْقَاعِدِينَ
wa-law arādū al-khurūja la-aʿaddū lahu ʿuddatan wa-lākin kariha Allāhu inbiʿāthahum fa-thabbaṭahum wa-qīla uqʿudū maʿa al-qāʿidīna
Translation:
“Had they intended to go out, they would certainly have prepared equipment and provisions for it; but The God disliked their setting out and held them back, and it was said: Sit with those who remain seated.”
The verse concerns a group that failed to accompany the Prophet in the departure and confrontation under discussion.
The Qur’an does not stop at the outward result of their not departing.
It first addresses their intention and preparation.
It then states the divine dislike of their departure and restraint of them.
Finally, it reports the statement uqʿudū maʿa al-qāʿidīn.
This sequence matters for understanding the root.
Wa-law arādū al-khurūj
The verse begins with a conditional construction.
Had they truly wanted to depart, they would have prepared.
The construction connects intention and preparation in that particular situation.
Their failure to prepare indicates that this group lacked a serious intention to depart.
This must not become an absolute rule about all people and circumstances.
Someone may sincerely wish to participate but be unable to obtain equipment because of illness, poverty, lack of transport, or another uncontrollable obstacle.
The Qur’an itself separately considers such people in Al-Tawbah 9:91 and Al-Tawbah 9:92.
Al-Tawbah 9:46 therefore judges a specific group whose conduct and intention are understood in context.
La-aʿaddū lahu ʿuddah
Aʿaddū derives from ʿ D D and here concerns preparing equipment and readiness.
ʿUddah denotes the means and resources needed for the action.
This can include provisions, transport, and necessary equipment.
The wording itself does not specify every item’s number or kind.
Nor does ʿuddah mean inward motivation; it names the means and preparedness supplied for action.
The verse concerns intention and practice: serious intention in those circumstances should have produced some preparation to depart.
Preparation alone likewise does not prove everyone’s true intention in every circumstance.
Someone may obtain equipment for another purpose.
Lack of preparation here is therefore presented alongside other contextual evidence of the group’s conduct.
5. Kariha Allāhu inbiʿāthahum: dislike of their departure
The verse continues:
«وَلَٰكِنْ كَرِهَ اللَّهُ انْبِعَاثَهُمْ»
wa-lākin kariha Allāhu inbiʿāthahum
But The God disliked their setting out.
The dislike is attributed to The God.
Inbiʿāth derives from the independent root B ʿ TH and is Form VII.
It concerns rising, beginning to move, or setting out for an undertaking.
Here the group’s movement and departure to accompany others is meant.
Inbiʿāth and tathbīṭ must therefore be distinguished.
Inbiʿāth expresses movement and being stirred to action.
Tathbīṭ expresses restraint from that movement.
Their juxtaposition clarifies the action’s direction and what prevents it.
Why did The God dislike their departure?
The next verse gives a clearer answer.
Al-Tawbah 9:47
Verse text:
لَوْ خَرَجُوا فِيكُمْ مَا زَادُوكُمْ إِلَّا خَبَالًا وَلَأَوْضَعُوا خِلَالَكُمْ يَبْغُونَكُمُ الْفِتْنَةَ وَفِيكُمْ سَمَّاعُونَ لَهُمْ ۗ وَاللَّهُ عَلِيمٌ بِالظَّالِمِينَ
law kharajū fīkum mā zādūkum illā khabālan wa-la-awḍaʿū khilālakum yabghūnakumu al-fitnata wa-fīkum sammāʿūna lahum wa-Allāhu ʿalīmun bi-al-ẓālimīna
Translation:
“Had they gone out among you, they would have increased you only in disorder and corruption, and hurried about among you seeking discord for you; among you are those who would listen to them. The God knows the wrongdoers.”
This verse clarifies why the group’s participation was undesirable.
Joining the believers would have increased disorder and corruption.
They would also have moved among the group seeking to cause discord.
Their being kept from departing thus also concerns averting harm that their presence could have caused others.
This does not mean that TH B Ṭ itself translates as “preventing corruption.”
Hindering is the lexical meaning.
Preventing harmful consequences is a purpose and result understood from the following verse.
Khabāl and al-fitnah
Al-Tawbah 9:47 contains two independent words.
Khabāl concerns corruption, disorder, and disruption.
Fitnah here concerns causing turmoil and harm among people.
Neither should become the meaning of thabaṭa itself.
Tathbīṭ in Al-Tawbah 9:46 prevents the group’s departure.
Khabāl and fitnah in Al-Tawbah 9:47 are harms that could have followed their participation.
The distinction is essential for translation and reflection.
6. Fa-thabbaṭahum: direct meaning and manner of restraint
Fa-thabbaṭahum is the Form II verb thabbaṭa.
It is a third-person masculine singular past verb.
The preceding clause identifies its subject as The God.
The object suffix hum refers to the same group.
Fa connects it with the preceding statement.
The construction is therefore clear: The God disliked their setting out and held them back.
Does tathbīṭ mean physical compulsion?
The verb itself does not determine how restraint occurred.
Some Arabic uses involve an external obstacle.
Others concern the action becoming burdensome, weakened resolve, or reduced motivation.
Al-Ṭabarī relates the verse’s tathbīṭ to departure becoming burdensome, so that staying behind seemed preferable to travelling.
This explanation fits the root’s lexical field.
Al-Ṭabarī: burdensome departure and remaining behind
The verb alone does not establish a physical obstacle such as chains, illness, or a blocked route.
Nor can one particular psychological feeling, such as fear or laziness, certainly be identified as the sole cause.
The verse does not describe the precise process in detail.
It explicitly attributes the restraint to The God.
Divine action and human choice
An important issue is the relationship between the group’s conduct and divine restraint.
The verse first says that genuine intention to depart would have led them to prepare.
It then states the divine dislike of their departure and restraint of them.
The next verse describes the harm their presence would have caused.
One aspect should not be interpreted by erasing the other.
The text explicitly identifies The God as the agent of tathbīṭ.
It also discusses the group’s lack of preparation and undesirable conduct.
Explanation should not turn the divine restraint into an event unrelated to The God.
Nor does this verb alone establish that they had no will or responsibility, with conduct entirely outside their own choice and orientation.
The precise relationship between divine will and human freedom is broader, requiring consideration of the relevant passages on responsibility, guidance, and error.
Both aspects occur here and neither should be removed.
Does every failure to proceed indicate divine displeasure?
No; the verse does not establish that conclusion.
Illness sometimes prevents an undertaking.
Someone may lack the necessary means or ability.
Someone may also consciously refrain from a wrongful action after understanding the circumstances.
Outward resemblance alone does not equate these situations with the group in Al-Tawbah 9:46.
Here dislike of their departure is explicit, and the next verse describes its harmful potential.
Without such evidence, not every setback or failure to proceed can be attributed to divine tathbīṭ in this particular contextual sense.
7. Wa-qīla uqʿudū maʿa al-qāʿidīn: sitting instead of departing
The verse ends:
«وَقِيلَ اقْعُدُوا مَعَ الْقَاعِدِينَ»
wa-qīla uqʿudū maʿa al-qāʿidīna
And it was said: Sit with those who remain seated.
Qīla is a passive past verb.
It means “it was said.”
The construction does not name the speaker.
Who said this?
Early explanations propose several possibilities.
Some attribute it to the group itself or its companions.
Others connect it with the Prophet’s permission or words.
Another explanation treats it as expressing a condition The God brought about for them.
These differences show that the passive qīla should not be overlooked.
“It was said” is preferable as a direct translation to “The God told them” or “the Prophet ordered them,” since this clause does not explicitly identify its speaker.
The statement contextually follows divine restraint and concerns the group’s remaining behind.
That connection alone does not change the verb’s passive construction.
Al-Qurṭubī: possible speakers behind qīla
Thabaṭa and qaʿada
Qaʿada is an independent root concerning sitting or remaining, in contrast with rising and moving.
Thabaṭa concerns hindering or slowing action.
Tathbīṭ here prevents departure; quʿūd expresses the resulting remaining behind.
The words are therefore distinct.
Someone can sit without another person restraining them.
Someone can also be prevented from one action while remaining active in others.
This verse brings restraint from departure and remaining with those seated into one specific context.
8. Blameworthy nonparticipation and genuine inability
In Al-Tawbah 9:46, the group’s failure to prepare forms part of the evidence that it lacked serious intention.
The Qur’an treats genuinely incapable people separately.
Al-Tawbah 9:91
Verse text:
لَيْسَ عَلَى الضُّعَفَاءِ وَلَا عَلَى الْمَرْضَىٰ وَلَا عَلَى الَّذِينَ لَا يَجِدُونَ مَا يُنْفِقُونَ حَرَجٌ إِذَا نَصَحُوا لِلَّهِ وَرَسُولِهِ ۚ مَا عَلَى الْمُحْسِنِينَ مِنْ سَبِيلٍ ۚ وَاللَّهُ غَفُورٌ رَحِيمٌ
laysa ʿalā al-ḍuʿafāʾi wa-lā ʿalā al-marḍā wa-lā ʿalā alladhīna lā yajidūna mā yunfiqūna ḥarajun idhā naṣaḥū li-Allāhi wa-rasūlihi mā ʿalā al-muḥsinīna min sabīlin wa-Allāhu ghafūrun raḥīmun
Translation:
“There is no blame on the weak, the sick, or those who find nothing to spend, provided they are sincere towards The God and His Messenger. There is no ground for censure against those who do good; The God is Forgiving and Merciful.”
This verse establishes an important boundary.
Those absent from a departure or social responsibility do not all share the same reasons or responsibility.
Someone may be able to participate but fail to fulfil a responsibility through lack of proper intention.
Another may wish to participate but be prevented by illness or lack of resources.
The outward result of not going therefore cannot alone establish intentions or the value of conduct.
Al-Tawbah 9:92 also describes people who wished to accompany the others but lacked transport, returning in grief.
They differ from the group whose lack of preparation and harmful potential are discussed in Al-Tawbah 9:46.
Does all sluggishness warrant blame?
Arabic thabaṭa can involve physical slowness or inability.
Physical inability is not inherently sinful.
Intentionally discouraging others from good action or knowingly evading responsibility, however, can be morally assessed.
Ability, intention, practical opportunity, and actual conduct must be distinguished.
TH B Ṭ itself expresses being held back or hindering action; moral responsibility is understood through circumstances and conduct.
9. Is tathbīṭ always negative?
In many social uses tathbīṭ has negative associations, since it deters someone from an intended action.
Creating groundless fear to deter others from helping someone in need, for example, can be harmful.
A negative value is nevertheless not a fixed component of the root.
Where someone intends harm, preventing them can have a beneficial result.
In Al-Tawbah 9:46, The God dislikes and prevents a group’s departure. Al-Tawbah 9:47 clarifies that their participation could have harmed others.
Tathbīṭ here is associated with preventing an undesirable outcome.
This does not establish that every instance of tathbīṭ in human life is commendable.
Deterring good action and preventing harmful action
Suppose someone intends to travel to assist disaster victims.
Deterring that person out of envy to obstruct assistance can be wrong.
Conversely, someone unprepared to enter a dangerous environment may endanger others through their presence; holding them back can be responsible.
Both involve prevention.
Their moral value follows from the action’s object, cause, and consequence.
The distinction helps explain Al-Tawbah 9:46 without replacing the word’s historical and Qur’anic meaning with modern examples.
11. Proposed equivalents for Forqan
For thabaṭahu ʿani al-amr, “held him back from the undertaking,” “slowed his action,” or “prevented him from acting” fits.
For thabbaṭa, “held back,” “dissuaded from action,” or contextually “slowed and weakened his movement” is suitable.
For tathbīṭ, “restraining action,” “slowing progress,” or contextually “weakening resolve to act” fits.
Intransitive thabiṭa can mean “became sluggish,” “slowed,” or “became heavy and weak in action.”
Descriptive thabiṭ can be rendered “slow,” “sluggish in movement,” or “slack in action.”
For tathabbaṭa, “was held back,” “stopped,” or “paused” is suitable.
Athbaṭahu al-maraḍu can mean “illness kept him from activity” or “illness gripped and weakened him.”
Proposed translation of the Qur’anic occurrence
Al-Tawbah 9:46
Main phrase:
«وَلَٰكِنْ كَرِهَ اللَّهُ انْبِعَاثَهُمْ فَثَبَّطَهُمْ»
wa-lākin kariha Allāhu inbiʿāthahum fa-thabbaṭahum
But The God disliked their setting out and held them back.
Proposed translation:
“But The God disliked their setting out and held them back.”
This rendering preserves several distinctions.
First, the dislike is attributed to The God.
Second, inbiʿāth retains movement and rising to action.
Third, fa-thabbaṭahum is rendered as holding back.
Fourth, no particular mechanism—fear, illness, laziness, or imprisonment—is added without evidence.
Fa-thabbaṭahum should not become “they themselves acted lazily,” which removes the construction’s explicit divine agency.
“The God compelled them to have no choice” likewise exceeds the verb’s direct meaning.
Explanation must consider the relationship between divine restraint and their conduct and will.
Proposed complete translation
“Had they intended to go out, they would certainly have prepared equipment and provisions for it; but The God disliked their setting out and held them back, and it was said: Sit with those who remain seated.”
Wa-qīla retains its passive form; no speaker is named without explicit evidence.
Al-qāʿidīn is rendered as those remaining seated, since the word alone does not establish that everyone had the same reason or responsibility for not going.
12. Conclusion
Arabic TH B Ṭ concerns slowness, sluggishness, failure to proceed, and preventing someone from an action.
Al-Khalīl explains tathbīṭ through diverting someone and keeping them from an undertaking.
Al-Zajjāj emphasises turning a person away from an action they are doing or intend.
Other lexical sources record slowing, obstruction, sluggish movement, and being caught in a state that limits progress.
Tathbīṭ can involve an external cause or inward state, but does not always determine the manner of restraint.
Some lexical sources quote yuthabbiṭ in Labīd’s verse, whereas reliable editions also record yubaṭṭiʾ. It is therefore not conclusive evidence for pre-Islamic use of this root without acknowledging the variants.
The root occurs only once in the Qur’an, as fa-thabbaṭahum in Al-Tawbah 9:46.
A group that had failed to prepare for departure remained behind.
The Qur’an attributes dislike of their departure to The God and says He held them back.
Al-Tawbah 9:47 describes the harmful consequences of their participation: increased disorder, corruption, and discord among the believers.
Their restraint thus concerns preventing those consequences.
Thabaṭa itself is not restricted lexically to preventing discord; that purpose follows from the next verse.
Blameworthy, deliberate nonparticipation must also be distinguished from genuine inability. Al-Tawbah 9:91 and Al-Tawbah 9:92 separately discuss illness, weakness, and lacking the means to accompany others.
Not going or being unprepared alone does not conclusively establish bad intention without attention to circumstances and ability.
Final root definition: TH B Ṭ denotes becoming slow, sluggish, or unable to proceed with an action and, transitively, restraining, slowing, or obstructing someone’s progress.
The distinctive feature is an obstacle arising or being placed in the way of action, rather than merely standing still, every delay, or necessarily laziness or moral weakness.
Qur’anic fa-thabbaṭahum means “so He held them back.”
This preserves the verb’s direct meaning and explicit attribution to The God; the reason for restraint, lack of preparation, and potential consequences of participation must be understood from the surrounding Al-Tawbah passages.
For Forqan, “holding back from action or movement” is therefore the most appropriate basic definition of TH B Ṭ.
