Core Meaning
The root ن س ي points to forgetting, losing from remembrance, leaving something outside attention, and removing it from the field of mental and practical presence.
In the Qur'an, nasyan is not always a natural weakness of memory. Sometimes a human being forgets something unintentionally. But sometimes a truth, covenant, warning, or responsibility is pushed so far out of attention and action that it is as if the person has forgotten it.
For this reason, nasyan in the Qur'an can have three levels: mental forgetting, meaning something does not remain present in memory; attentional forgetting, meaning something is known but moved away from the center of attention; and ethical and practical forgetting, meaning a truth or covenant is removed from behavior so thoroughly that it no longer has any effect in life.
The shared core of the root is this: something that should be present, preserved, and attended to is moved out of the field of remembrance, attention, covenant, or action.
Important Forms
نسي is a past-tense verb and points to forgetting or leaving something outside attention:
وَلَقَدْ عَهِدْنَا إِلَىٰ آدَمَ مِن قَبْلُ فَنَسِيَ
And We had made a covenant with Adam before; then he forgot.
Ta-Ha 20:115
نسوا is the plural past form:
نَسُوا اللَّهَ فَنَسِيَهُمْ
They forgot The God, so He left them aside.
At-Tawbah 9:67
تنسى is a present-tense verb and points to forgetting:
سَنُقْرِئُكَ فَلَا تَنسَىٰ
We will soon recite to you, so you will not forget.
Al-A'la 87:6
لا تنس is a prohibitive form:
وَلَا تَنسَ نَصِيبَكَ مِنَ الدُّنْيَا
And do not forget your share of the world.
Al-Qasas 28:77
أنسى and أنساهم are from form IV and point to making forgotten or causing forgetting:
اسْتَحْوَذَ عَلَيْهِمُ الشَّيْطَانُ فَأَنسَاهُمْ ذِكْرَ اللَّهِ
Satan gained hold over them, so he made them forget the remembrance of The God.
Al-Mujadilah 58:19
نسيا is a noun and points to something forgotten, abandoned, considered insignificant, or neglected:
يَا لَيْتَنِي مِتُّ قَبْلَ هَٰذَا وَكُنتُ نَسْيًا مَّنسِيًّا
If only I had died before this and had been something forgotten and utterly left out of memory.
Maryam 19:23
منسيا is a passive noun and points to something abandoned and no longer attended to.
نسيا also appears in relation to The God:
وَمَا كَانَ رَبُّكَ نَسِيًّا
And your Lord is never forgetful.
Maryam 19:64
This verse is the criterion for understanding expressions such as فنسيهم and إنا نسيناكم.
Linguistic Note
Nasyan in the Qur'an is not only the absence of information in memory. This root works with the presence and absence of meaning. Something that should be present in mind, heart, covenant, or action leaves the field of attention.
This leaving of presence has different forms. Sometimes it is natural and human, as in the forgetting of the fish by Musa's companion. Sometimes it is tied to weakness in preserving covenant, as in Adam's forgetting. Sometimes it is the result of heedlessness and continued inattention.
Sometimes something has not been completely erased from memory, but no longer affects decision and behavior. Sometimes the human being recognizes truth but lives as though he has never heard it. Thus a person may remember something verbally, but because no practical trace of it remains, at the Qur'anic level he has forgotten it.
Material Image
The material image of this root is something abandoned and no longer attended to. A caravan leaves a station, and something considered unimportant remains behind. No one returns to retrieve it, and it enters the category of things cast aside and forgotten.
This image is clear in the expression نسيا منسيا: something not only forgotten, but abandoned and fallen outside the attention of others.
Another image is a covenant or sign that should have remained constantly present before the human being, but has been pushed to the margins. The writing still exists, but no one opens it or acts by it.
In the ethical field, nasyan is this falling out of priority. A human being may not verbally deny The God, the Hereafter, covenant, or warning, but he pushes it so far to the margins that it has no presence in his choices.
Classical Usage
In classical Arabic, نسي points to forgetting, losing from memory, and leaving something outside attention.
النسي is also used for something neglected, abandoned, considered insignificant, or forgotten during departure and travel. Therefore, abandonment and falling outside attention are part of the old field of this root.
This material meaning fits the Qur'anic use of نسيا منسيا: something cast aside that no one attends to anymore.
The root ن س ي (nasiya) must not be merged with the root ن س أ (nasa'a). ن س أ (nasa'a) relates to delaying and postponing. There may be an interpretive connection between forgetting and postponing in human experience, but in root analysis they must be kept separate.
Adam's Forgetting and Weakness in Preserving Covenant
The Qur'an says:
وَلَقَدْ عَهِدْنَا إِلَىٰ آدَمَ مِن قَبْلُ فَنَسِيَ وَلَمْ نَجِدْ لَهُ عَزْمًا
And We had made a covenant with Adam before; then he forgot, and We did not find in him firm resolve.
Ta-Ha 20:115
In this verse, nasyan is connected with covenant and resolve. Adam did not merely forget a piece of mental information. A covenant that should have been present in his behavior moved away from the center of attention and decision.
The pairing of فنسى with ولم نجد له عزما shows that nasyan here is tied to weakness in preserving covenant. Something that should have directed decision lost its presence.
This verse shows nasyan as part of human vulnerability. A human being may recognize a truth, but if he does not preserve it through dhikr, resolve, and vigilance, it leaves the center of his conduct.
Forgetting The God
In Surah At-Tawbah, it says:
نَسُوا اللَّهَ فَنَسِيَهُمْ
They forgot The God, so He left them aside.
At-Tawbah 9:67
Forgetting The God in this verse cannot mean only that His name was erased from memory. They may know His name, but they have removed His presence, covenant, command, and responsibility before Him from their life.
Forgetting The God means living as though there is no oversight, account, covenant, or answerability before Him.
But فنسيهم cannot mean mental forgetting by The God, because the Qur'an explicitly says:
وَمَا كَانَ رَبُّكَ نَسِيًّا
And your Lord is never forgetful.
Maryam 19:64
So فنسيهم means He left them aside, removed special support and mercy from them, or entrusted them to the consequence of the path they had chosen.
This contrast is based on the correspondence between action and consequence: they removed the presence of The God from their life, and as a result they were left outside special divine support.
Forgetting the Self
The Qur'an says:
وَلَا تَكُونُوا كَالَّذِينَ نَسُوا اللَّهَ فَأَنسَاهُمْ أَنفُسَهُمْ
And do not be like those who forgot The God, so He made them forget themselves.
Al-Hashr 59:19
This verse is one of the deepest uses of the root. Forgetting The God leads to forgetting the self. When the human being removes his source, aim, covenant, and answerability, he no longer knows his own reality rightly.
Forgetting the self does not mean forgetting one's name or outward identity. The human being forgets his dignity, outcome, ethical capacity, and real responsibility. He may see immediate interest, but in that very path he ruins his own being.
This verse shows that knowing the self in the Qur'an is not separated from knowing the human being's relation to the Lord. Whoever removes that relation also loses the criterion by which real benefit and harm are measured.
Satan's Hold and the Forgetting of Dhikr
The Qur'an says:
اسْتَحْوَذَ عَلَيْهِمُ الشَّيْطَانُ فَأَنسَاهُمْ ذِكْرَ اللَّهِ
Satan gained hold over them, so he made them forget the remembrance of The God.
Al-Mujadilah 58:19
Satan's gaining hold does not mean the complete destruction of human choice. The Qur'an repeatedly shows that Satan invites, whispers, and deceives the human being, but cannot force him with absolute compulsion.
Satanic domination expands when the human being opens the path of attention, habit, desire, and obedience to it. Persistence in inattention, lying, self-deception, and following desires weakens the presence of dhikr, until Satan comes to dominate the field of human attention.
So human responsibility remains. Istihwadh is not a one-sided and coercive relation; through repeated acceptance of whispering, the human being prepares the ground for domination.
فأنساهم ذكر الله means the remembrance of The God left the center of their attention and decision. They may still have His name on their tongues, but His remembrance no longer guides their behavior.
Forgetting the Day of Meeting
The Qur'an says:
فَذُوقُوا بِمَا نَسِيتُمْ لِقَاءَ يَوْمِكُمْ هَٰذَا إِنَّا نَسِينَاكُمْ
So taste because you forgot the meeting of this Day of yours; We have left you aside.
As-Sajdah 32:14
Forgetting the Day of Meeting means living without practical attention to account and outcome. They may have heard speech about the Hereafter, but they removed it from the center of their decisions.
إنا نسيناكم also does not mean divine weakness of memory. In light of وما كان ربك نسيا, it means leaving them to the consequence of that same indifference.
This verse shows that ethical forgetting can affect a human being's future. When the outcome is removed from today's decision, the human being faces the result of that removal on the Day when consequences appear.
Preserving Recitation and Divine Will
The Qur'an says to the Messenger:
سَنُقْرِئُكَ فَلَا تَنسَىٰ
We will soon recite to you, so you will not forget.
Al-A'la 87:6
Then it says:
إِلَّا مَا شَاءَ اللَّهُ ۚ إِنَّهُ يَعْلَمُ الْجَهْرَ وَمَا يَخْفَىٰ
Except what The God wills. Indeed, He knows what is open and what is hidden.
Al-A'la 87:7
These verses speak of recitation and its preservation. فلا تنسى is a promise of preservation and firm establishment, but إلا ما شاء الله removes absolute independence from the human being and keeps everything under divine will.
From this phrase itself, one should not derive a theory of deleted verses or abrogated recitation. The verse can state that the Messenger's preservation is by the will and support of The God, not by an independent property of human memory.
So the root entry should remain at this level: nasyan here has a memory-related meaning, and preservation of recitation is attributed to divine will and teaching.
Forgetting in the Story of Musa and His Companion
In the story of Musa and his companion, it says:
فَإِنِّي نَسِيتُ الْحُوتَ وَمَا أَنسَانِيهُ إِلَّا الشَّيْطَانُ أَنْ أَذْكُرَهُ
I forgot the fish, and nothing made me forget to mention it except Satan.
Al-Kahf 18:63
In this verse, nasyan stands opposite dhikr. Something should have been remembered and reported, but it left the field of attention.
This use shows that nasyan can be ordinary and human. Even so, that limited forgetting may change the path of travel or keep an important sign outside attention for a time.
Nasyan Mansiyya: Complete Abandonment From Attention
Maryam says in the difficult moment of childbirth:
يَا لَيْتَنِي مِتُّ قَبْلَ هَٰذَا وَكُنتُ نَسْيًا مَّنسِيًّا
If only I had died before this and had been something forgotten and completely out of memory.
Maryam 19:23
نسيا منسيا is an image of something not merely forgotten, but abandoned, cast aside, and no longer attended to by anyone.
This expression shows the intensity of Maryam's psychological pressure. She wishes to be completely outside people's gaze, judgment, and memory, like something that never had importance and no one searches for.
This verse is one of the clearest evidences that nasyan can be connected with abandonment and neglect.
Forgetting Divine Warnings
The Qur'an says about some groups:
فَلَمَّا نَسُوا مَا ذُكِّرُوا بِهِ فَتَحْنَا عَلَيْهِمْ أَبْوَابَ كُلِّ شَيْءٍ
So when they forgot what they had been reminded of, We opened for them the gates of everything.
Al-An'am 6:44
Here nasyan stands opposite tadhkir. They heard the warning, but removed it from attention and behavior.
This forgetting is not merely a defect of memory. It is practical indifference toward reminder. Even the opening of blessings afterward is not necessarily a sign of approval; it may be a trial that lets them continue in that same inattention.
Forgetting a Portion of the Reminder
About a group from the People of the Book, it says:
فَنَسُوا حَظًّا مِّمَّا ذُكِّرُوا بِهِ
So they forgot a portion of what they had been reminded of.
Al-Ma'idah 5:13
حظا points to a share or portion of what they had been reminded of. The verse says a portion of that reminder left their presence.
This expression does not necessarily mean a conscious and sudden deletion. Nasyan can happen gradually: continuous inattention, breaking covenant, preferring interests, becoming accustomed to sin, and abandoning action can remove part of the message from the living structure of a community.
A society may preserve words, while losing the guiding and ethical role of part of the message. In such a case, a text or memory remains, but its real portion in life has been forgotten.
If conscious deletion or concealment is intended, the Qur'an has more precise words for it, such as kitman, tahrif, or nabdh. Nasyan here emphasizes the result: part of the reminder has left attention and action.
The God Is Not Forgetful
One foundational verse for regulating all uses of this root in relation to The God is this:
وَمَا كَانَ رَبُّكَ نَسِيًّا
And your Lord is never forgetful.
Maryam 19:64
This verse negates mental forgetting from the realm of The God. His knowledge is not limited, worn down, or subject to absence.
Therefore, wherever the Qur'an speaks of فنسيهم or إنا نسيناكم, it must be understood within the frame of leaving aside, depriving from special support, or entrusting to the consequence of action; not mental forgetting.
This principle clarifies the fundamental difference between human nasyan and the corresponding use of the root in relation to The God.
Nunsiha in Al-Baqarah 2:106 and the Boundary Between N S Y and N S A
In Al-Baqarah, it says:
مَا نَنسَخْ مِنْ آيَةٍ أَوْ نُنسِهَا نَأْتِ بِخَيْرٍ مِّنْهَا أَوْ مِثْلِهَا
Whatever sign We replace or cause to be forgotten, We bring better than it or like it.
Al-Baqarah 2:106
In the well-known reading, ننسها is connected with nasyan and can point to causing to be forgotten or removing from presence. But another reading with hamzah is also reported: ننسأها, from the root ن س أ (nasa'a), meaning to delay.
These two roots must not be treated as one. ن س ي (nasiya) relates to forgetting and leaving presence. ن س أ (nasa'a) relates to delaying and moving time back.
The existence of two readings produces two different semantic possibilities: one related to nasyan and the other to delay. This difference should not be used to prove that the two words share one root.
This entry is about ن س ي (nasiya); therefore the full study of ن س أ (nasa'a) should be done in a separate entry.
Similar Uses
Nasyan is sometimes a natural weakness of memory, as with forgetting the fish in the story of Musa and his companion.
Sometimes it is weakness in preserving covenant and resolve, as with Adam's forgetting.
Sometimes it is leaving warning outside attention and action, as in نسوا ما ذكروا به.
Sometimes it is practical indifference to The God and the Hereafter, as in نسوا الله or نسيتم لقاء يومكم.
Sometimes it is the result of Satan gaining hold over the field of attention, as in فأنساهم ذكر الله, without human responsibility and choice being completely removed.
Sometimes it is being left to the consequence of one's own choice, as in فنسيهم or إنا نسيناكم.
Sometimes it points to something completely abandoned and forgotten, as in نسيا منسيا.
Sometimes it relates to preserving memory and recitation, as in فلا تنسى.
Sometimes it is the gradual removal of part of a message from the life and action of a community, as in فنسوا حظا مما ذكروا به.
Grammar and Structure
In فنسي ولم نجد له عزما, nasyan is tied to weakness of resolve. This shows that the issue is not only memory, but preserving covenant in will and action.
In نسوا الله فنسيهم, the repetition of the root creates a corresponding structure. They removed the presence of The God from their life, and consequently they were left to the consequence of their choice.
In فأنساهم أنفسهم, form IV shows that forgetting the self became the consequence of forgetting The God. An ethical and causal relation is established between the two forms of nasyan.
In أنساهم ذكر الله, dhikr is what has left their field of presence.
In وما كان ربك نسيا, the negating structure fundamentally removes nasyan from the realm of the Lord.
In لا تنس نصيبك, the prohibition shows that preserving attention to one's proper worldly share is also a responsibility.
In نسيا منسيا, the pairing of noun and passive noun intensifies the forgetting and abandonment: something forgotten and completely outside memory and attention.
In نسوا ما ذكروا به, the contrast between نسي and ذكر is clear. Tadhkir brings something into presence; nasyan removes it from presence.
In فنسوا حظا, the object of forgetting is “a portion” of the reminder, not necessarily all of it. This structure allows for some parts remaining while other parts leave attention.
In فلا تنسى إلا ما شاء الله, the exception shows the dependence of the Messenger's preservation on divine will and negates intrinsic independence.

Summary
The root ن س ي indicates forgetting, losing from memory, leaving something outside attention, and removing it from the field of mental presence, covenant, and action.
In the Qur'an, nasyan is sometimes a natural weakness of memory. But in many places it is an ethical and practical state: forgetting covenant, The God, the Hereafter, warning, the self, or part of the message. A human being may know the words of something, but because that truth has no presence in his behavior, at the Qur'anic level he has forgotten it.
With وما كان ربك نسيا, the Qur'an negates mental forgetting from The God. Therefore, فنسيهم and إنا نسيناكم mean leaving human beings to the consequence of their choice, not weakness in divine memory.
The difference between nasyan and ghaflah is that ghaflah is inattention to a present matter, while nasyan is its leaving the field of remembrance and action. The difference from sahw is that sahw is usually temporary distraction, while nasyan can become lasting and structural. The difference from tark is that tark is usually more conscious, while nasyan can be unintended, gradual, or practical.
The root ن س أ (nasa'a) must also be kept separate from ن س ي (nasiya). ن س أ (nasa'a) relates to delay, while ن س ي (nasiya) relates to forgetting and leaving presence.
In Forqan translation, نسي should not always be translated only as “forgot.” Depending on context, “lost from memory,” “removed from attention,” “left aside,” “abandoned,” or “practically ignored” may be more precise.
