The Qur’anic Root B L W
Testing in lived situations: good, evil, balāʾ, and wearing away
The root ب ل و occurs in the Qur’an mainly in the sense of testing: a person encounters a situation in which ability, choice, or conduct is put to the test. Good and evil, prosperity and constraint, and responsibilities entrusted to a person can each serve as means of testing. Alongside these uses, يَبْلَىٰ in Ṭā Hā 20:120 denotes wearing away.
The Qur’anic morphological index records this family 38 times, including يَبْلَىٰ: 30 verbs, six occurrences of the noun بَلَاء, and two of the active participle مُبْتَلِي. Eight of the verbs belong to form VIII. يُبْلِيَ in Al-Anfāl 8:17 is form IV, while يَبْلَىٰ in Ṭā Hā 20:120 comes from بَلِيَ. Grouping these forms under one entry helps locate all the occurrences; it does not by itself establish the historical relationship between testing and wearing away.
For the testing branch, an initial definition is:
B L W: to subject a person, thing, or action to testing or examination, so that its quality, response, or condition becomes known in an actual situation. Such testing may involve good or evil, ease or constraint, a command, responsibility, a benefit, or hardship. Depending on construction and context, balāʾ may denote the test itself, a trying hardship, or a benefit or favor that someone receives.
For the other branch:
بَلِيَ / يَبْلَىٰ: to become old, worn, or subject to deterioration.
In the passive لَتُبْلَوُنَّ in Āl ʿImrān 3:186, the word’s shape alone does not distinguish form I from form IV. The morphological index assigns it to form IV; its count of “two form IV occurrences” therefore depends on that analysis. This analytical distinction does not change the total of 38 occurrences.
Qur’anic forms
Two branches in early Arabic: testing and wearing away
In Zuhayr ibn Abī Sulmā’s pre-Islamic poem beginning “صحا القلب عن سلمى,” the following verse praises two men. The wording below follows the dīwān; a variant beginning جَزَى اللَّهُ and continuing وَأَبْلَاهُمَا is also transmitted:
رَأَى اللَّهُ بِالإِحْسَانِ مَا فَعَلَا بِكُمْ
فَأَبْلَاهُمَا خَيْرَ الْبَلَاءِ الَّذِي يَبْلُو
“The God saw the good that the two of them did for you, and bestowed on them the best good that He bestows.”
Here أَبْلَاهُمَا and الْبَلَاءِ occur in a setting of praise and beneficence. Their context provides evidence for the family’s use in bestowing good or favorable treatment. Source: the Dīwān of Zuhayr, the poem “صحا القلب عن سلمى,” the verse beginning “رأى الله بالإحسان…”.
The wearing-away branch also appears in a poem by Labīd ibn Rabīʿah, whose life spanned the pre-Islamic and early Islamic periods. The precise date of this verse has not been established here:
بَلِينَا وَمَا تَبْلَى النُّجُومُ الطَّوَالِعُ
وَتَبْقَى الْجِبَالُ بَعْدَنَا وَالْمَصَانِعُ
“We wear away, while the rising stars do not wear away; the mountains and built works remain after us.”
In بَلِينَا / تَبْلَى, human aging and passing away stand against the endurance of the surroundings. This is evidence for the meaning “wear away.” The two poetic verses document two early uses; they do not by themselves establish that one historically developed from the other. Source: Labīd’s poem beginning “بلينا وما تبلى النجوم الطوالع,” opening verse.
Testing to recognize capacity and sound judgment
One of the clearest examples of human testing concerns orphans:
وَابْتَلُوا الْيَتَامَىٰ حَتَّىٰ إِذَا بَلَغُوا النِّكَاحَ فَإِنْ آنَسْتُمْ مِنْهُمْ رُشْدًا فَادْفَعُوا إِلَيْهِمْ أَمْوَالَهُمْ وَلَا تَأْكُلُوهَا إِسْرَافًا وَبِدَارًا أَنْ يَكْبَرُوا وَمَنْ كَانَ غَنِيًّا فَلْيَسْتَعْفِفْ وَمَنْ كَانَ فَقِيرًا فَلْيَأْكُلْ بِالْمَعْرُوفِ فَإِذَا دَفَعْتُمْ إِلَيْهِمْ أَمْوَالَهُمْ فَأَشْهِدُوا عَلَيْهِمْ وَكَفَىٰ بِاللَّهِ حَسِيبًا
“And test the orphans until, when they reach marriageable age, if you perceive sound judgment in them, hand over their property to them. Do not consume it wastefully and hastily before they grow up. Whoever is self-sufficient should refrain, and whoever is poor may take in a recognized, proper manner. When you hand over their property, have witnesses present; The God suffices as reckoner.”
Al-Nisāʾ 4:6
Here ابْتَلُوا has a practical meaning. The orphan is placed in a situation in which ability and sound judgment can be assessed before a decision is made about handing over the property.
Testing here is a way of recognizing quality through practical experience. The issue is the orphan’s readiness to manage their own property, demonstrated through discernible conduct.
Good and evil as means of testing
In Al-Anbiyāʾ, both sides of this testing appear together:
كُلُّ نَفْسٍ ذَائِقَةُ الْمَوْتِ وَنَبْلُوكُمْ بِالشَّرِّ وَالْخَيْرِ فِتْنَةً وَإِلَيْنَا تُرْجَعُونَ
“Every soul will taste death. We test you with evil and good as a trial, and to Us you will be returned.”
Al-Anbiyāʾ 21:35
This verse is fundamental to understanding balāʾ: testing may involve evil, and it may also involve good.
Al-Fajr presents this in more concrete terms:
فَأَمَّا الْإِنْسَانُ إِذَا مَا ابْتَلَاهُ رَبُّهُ فَأَكْرَمَهُ وَنَعَّمَهُ فَيَقُولُ رَبِّي أَكْرَمَنِ وَأَمَّا إِذَا مَا ابْتَلَاهُ فَقَدَرَ عَلَيْهِ رِزْقَهُ فَيَقُولُ رَبِّي أَهَانَنِ كَلَّا بَلْ لَا تُكْرِمُونَ الْيَتِيمَ
“As for the human being, when his Lord tests him, honors him, and grants him blessings, he says, ‘My Lord has honored me.’ But when He tests him and restricts his provision, he says, ‘My Lord has humiliated me.’ No! Rather, you do not honor the orphan.”
The verb ابْتَلَاهُ occurs in both situations: prosperity and blessing, as well as restricted provision.
Possessing resources is therefore not in itself a final sign of divine approval, nor is constraint in itself a sign of humiliation. Both can be situations of testing.
In Al-Aḥzāb 33:11, the passive form VIII verb is accompanied by a description of the situation’s severity:
هُنَالِكَ ابْتُلِيَ الْمُؤْمِنُونَ وَزُلْزِلُوا زِلْزَالًا شَدِيدًا
“There the believers were tested and shaken with a severe shaking.” The severity is explicit in the remainder of the sentence; ابْتُلِيَ alone does not determine the degree or duration of the test.
What has been given as a field of testing
Al-Anʿām states:
وَهُوَ الَّذِي جَعَلَكُمْ خَلَائِفَ الْأَرْضِ وَرَفَعَ بَعْضَكُمْ فَوْقَ بَعْضٍ دَرَجَاتٍ لِيَبْلُوَكُمْ فِي مَا آتَاكُمْ إِنَّ رَبَّكَ سَرِيعُ الْعِقَابِ وَإِنَّهُ لَغَفُورٌ رَحِيمٌ
“It is He who has made you successors on the earth and raised some of you above others in degrees, to test you in what He has given you. Your Lord is swift in punishment, and He is forgiving, merciful.”
Al-Anʿām 6:165
Here what has been given is the field of testing: a person’s resources and position are connected with responsibility.
The same construction occurs in Al-Māʾidah 5:48:
لِيَبْلُوَكُمْ فِي مَا آتَاكُمْ
Differences in what people have received can thus belong to the sphere of responsibility and testing.
Testing through something real and within reach
Al-Māʾidah offers a particularly concrete example:
يَا أَيُّهَا الَّذِينَ آمَنُوا لَيَبْلُوَنَّكُمُ اللَّهُ بِشَيْءٍ مِنَ الصَّيْدِ تَنَالُهُ أَيْدِيكُمْ وَرِمَاحُكُمْ لِيَعْلَمَ اللَّهُ مَنْ يَخَافُهُ بِالْغَيْبِ فَمَنِ اعْتَدَىٰ بَعْدَ ذَٰلِكَ فَلَهُ عَذَابٌ أَلِيمٌ
“You who have believed, The God will certainly test you with some game that your hands and spears can reach, so that The God may know who fears Him in the unseen. Whoever transgresses after that will have a painful punishment.”
Al-Māʾidah 5:94
The test takes place in an actual situation: something is within reach, and a person must choose.
The accessibility of the game creates an occasion for a practical choice. In this use, testing takes place through what a person does.
The same attention to action appears in Hūd 11:7 and Al-Mulk 67:2:
لِيَبْلُوَكُمْ أَيُّكُمْ أَحْسَنُ عَمَلًا
“To test you as to which of you is best in action.” أَحْسَنُ عَمَلًا emphasizes the quality of action.
Testing and recognizing the quality of conduct
Testing can make the quality of a person’s conduct and position discernible. In some verses this outcome is expressed by a separate verb alongside نبلو:
For example:
وَلَنَبْلُوَنَّكُمْ حَتَّىٰ نَعْلَمَ الْمُجَاهِدِينَ مِنْكُمْ وَالصَّابِرِينَ وَنَبْلُوَ أَخْبَارَكُمْ
“We will certainly test you until We know those among you who strive and those who persevere, and We will test your reports.”
Muḥammad 47:31
In this sentence, نَبْلُوَ expresses testing, while نَعْلَمَ expresses knowing or recognizing. The object of testing at the end is أَخْبَارَكُمْ: reports concerning you and your actions. The two verbs distinguish testing from its outcome in knowledge.
In Al-Ṭāriq, the objects of testing are the hidden things:
يَوْمَ تُبْلَى السَّرَائِرُ
“On the day when hidden things are put to the test.”
Al-Ṭāriq 86:9
تُبْلَى is passive here, and السَّرَائِرُ is its grammatical subject. “Hidden things are put to the test” preserves the sentence’s construction; the disclosure of their quality describes an outcome of this examination.
Divine testing and the verb “to know”
In Al-Māʾidah 5:94 and Muḥammad 47:31, testing is accompanied by the verb “to know.” Translation should retain both verbs and their relationship:
In Muḥammad 47:31:
حَتَّىٰ نَعْلَمَ
“Until We know”; and in Al-Māʾidah 5:94:
لِيَعْلَمَ اللَّهُ
“So that The God may know.” These expressions concern striving, perseverance, and reverence in practical situations.
Lexically, ibtilāʾ means subjecting someone or something to a test. The relationship between knowing and the occurrence of an action requires consideration of the wider Qur’anic text. An explanation of that relationship should not silently replace “to know” in a translation.
The root B L W does not on its own supply a theory of divine knowledge.
Uses of the noun balāʾ
The noun بَلَاء occurs six times in the Qur’an. Qualifiers such as حَسَن, عَظِيم, and مُبِين, together with the event under discussion, help determine how each occurrence is understood.
Balāʾan ḥasanan: favorable treatment
Al-Anfāl states:
فَلَمْ تَقْتُلُوهُمْ وَلَٰكِنَّ اللَّهَ قَتَلَهُمْ وَمَا رَمَيْتَ إِذْ رَمَيْتَ وَلَٰكِنَّ اللَّهَ رَمَىٰ وَلِيُبْلِيَ الْمُؤْمِنِينَ مِنْهُ بَلَاءً حَسَنًا إِنَّ اللَّهَ سَمِيعٌ عَلِيمٌ
“You did not kill them, but The God killed them. You did not throw when you threw, but The God threw; and so that He might bestow on the believers a good benefit from Himself. The God is hearing, knowing.”
Al-Anfāl 8:17
In Al-Anfāl 8:17, بَلَاءً حَسَنًا occurs in a setting of assistance in a confrontation. “A good benefit” is a contextual translation emphasizing what the believers receive. “A good test” is another linguistic possibility; the qualifier حَسَنًا alone does not settle the choice.
In Zuhayr’s verse, too, خَيْرَ الْبَلَاءِ appeared in praise of beneficence. That evidence supports the possibility of a positive sense of balāʾ; each Qur’anic occurrence must still be read in its own sentence and context.
Balāʾun ʿaẓīm: hardship, testing, or a benefit?
The following expression occurs three times in the account of the Children of Israel: Al-Baqarah 2:49, Al-Aʿrāf 7:141, and Ibrāhīm 14:6.
وَفِي ذَٰلِكُمْ بَلَاءٌ مِنْ رَبِّكُمْ عَظِيمٌ
One occurrence is:
وَإِذْ نَجَّيْنَاكُمْ مِنْ آلِ فِرْعَوْنَ يَسُومُونَكُمْ سُوءَ الْعَذَابِ يُذَبِّحُونَ أَبْنَاءَكُمْ وَيَسْتَحْيُونَ نِسَاءَكُمْ وَفِي ذَٰلِكُمْ بَلَاءٌ مِنْ رَبِّكُمْ عَظِيمٌ
“And when We delivered you from Pharaoh’s people, who subjected you to terrible torment, slaughtering your sons and keeping your women alive; in that was a great trial from your Lord.”
Al-Baqarah 2:49
ذَٰلِكُمْ points back to an event in which both torment and deliverance are mentioned. If the torment is foregrounded, the hardship of the trial stands out; if deliverance is foregrounded, the benefit and release stand out. The whole event may also be the referent.
The translation above uses “a great trial.” Attention to the referent of ذَٰلِكُمْ explains why both hardship and deliverance enter the discussion. The root alone does not determine which aspect should be foregrounded.
Al-balāʾ al-mubīn: Abraham’s test
After Abraham’s dream and his readiness to carry it out, the text states:
إِنَّ هَٰذَا لَهُوَ الْبَلَاءُ الْمُبِينُ
“This is indeed the clear test.”
Al-Ṣāffāt 37:106
Here balāʾ refers to the situation in which Abraham is tested. Its difficulty is understood from the preceding narrative.
مُبِين qualifies الْبَلَاءُ, expressing clarity or manifestness. “Severe” would be a contextual description of the test, not a translation of مُبِين itself.
Balāʾun mubīn among the signs and benefits
The Qur’an also says of the Children of Israel:
وَآتَيْنَاهُمْ مِنَ الْآيَاتِ مَا فِيهِ بَلَاءٌ مُبِينٌ
“We gave them signs in which there was a clear test.”
Al-Dukhān 44:33
The preceding verses describe the deliverance of the Children of Israel from humiliating torment. Here, too, بَلَاءٌ مُبِينٌ occurs among signs given to them. The testing situation is thus connected with receiving those signs and benefiting from them.
Wearing away: mulkin lā yablā
In Ṭā Hā, Satan says to Adam:
فَوَسْوَسَ إِلَيْهِ الشَّيْطَانُ قَالَ يَا آدَمُ هَلْ أَدُلُّكَ عَلَىٰ شَجَرَةِ الْخُلْدِ وَمُلْكٍ لَا يَبْلَىٰ
“Then Satan whispered to him, saying, ‘Adam, shall I guide you to the tree of lasting life and a dominion that does not wear away?’”
Ṭā Hā 20:120
Here يَبْلَىٰ comes from بَلِيَ, “to become old or worn.” In مُلْكٍ لَا يَبْلَىٰ, the endurance of dominion is at issue.
Wearing away is intransitive: something itself becomes old or deteriorates. In testing, an agent tests someone or something. This semantic and grammatical difference matters when reading forms that resemble one another.
Testing and wearing away are examined together in this entry because the Qur’anic index groups them together. The concrete image of wearing away with age appeared in Labīd’s poem; for the testing branch, the evidence examined here does not establish one definite physical origin.
Translation choices for Forqan
For بَلَا / يَبْلُو, suitable translations in most contexts are:
“To test”
or
“to put to the test.”
An explanation may clarify that testing takes place through real situations, choices, and actions. That longer explanation need not be inserted into every verse translation.
For ابْتَلَىٰ, “tested” is also suitable. Form VIII alone does not establish that a test is necessarily more intense, prolonged, or wearing than one expressed by the simple verb.
For the active participle مُبْتَلِي, as in مُبْتَلِيكُمْ in Al-Baqarah 2:249 and لَمُبْتَلِينَ in Al-Muʾminūn 23:30:
“One who tests”
or, more naturally in some sentences,
“one who puts someone to the test.”
The translation of بَلَاء depends on context.
In Abraham’s account:
الْبَلَاءُ الْمُبِينُ
“The clear test” or “the manifest test.” Its difficulty can be explained separately in light of the narrative.
In the verses concerning the Children of Israel:
بَلَاءٌ عَظِيمٌ
The choice among “a great trial,” “a great hardship,” and “a great benefit” requires attention to the sentence’s referent. The word alone does not settle that choice.
In Al-Anfāl 8:17:
بَلَاءً حَسَنًا
“A good benefit” or “favorable treatment,” in light of the context of assistance; “a good test” remains another linguistic possibility.
يَوْمَ تُبْلَى السَّرَائِرُ
“On the day when hidden things are put to the test.” An explanation may describe the disclosure of the quality of what was hidden.
مُلْكٍ لَا يَبْلَىٰ
“A dominion that does not wear away.” Freedom from deterioration is the force of the expression.
Conclusion
The Qur’anic uses of B L W present different testing situations: assessing an orphan’s sound judgment, choosing how to act when game is within reach, using what one has been given, and responding to prosperity or restricted provision.
The core of the testing branch is testing or subjecting someone or something to examination. A person’s quality and response become discernible in that encounter; in some verses, knowing or recognizing appears as a separate verb alongside testing.
The noun balāʾ is understood through its qualifiers and context. Abraham’s test, the torment and deliverance of the Children of Israel, and the favorable treatment in Al-Anfāl are different situations. Translation should reflect those differences.
The branch بَلِيَ / يَبْلَىٰ denotes wearing away; its Qur’anic example is مُلْكٍ لَا يَبْلَىٰ. Early poetry also attests both bestowing good and wearing away. Establishing their historical relationship requires more evidence than their inclusion under a single dictionary entry.
B L W: in the testing branch, someone or something is subjected to examination; both good and evil can serve as means of that test. Depending on context, balāʾ denotes testing, a trying hardship, or favorable treatment. In the wearing-away branch, بَلِيَ / يَبْلَىٰ expresses becoming old or subject to deterioration.
