لَنْ and not in Arabic

فَقَالَ اِخْسَأْ، فَلَنْ تَعْدُوَ قَدْرَكَ

So he said, "Get out in disgrace; you will not exceed your limits."

فَلَنْ so will not

Two pieces fused: the front fa- continues the speech, and the rest is a particle that flatly negates a future action. That negator is strong and absolute, denying the action will ever happen, and it pushes the following verb into a special non-realis ending to mark it as ruled out.

From A Night with the Companions

فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِنْ يَكُنْهُ فَلَنْ تُسَلَّطَ عَلَيْهِ،

So the Prophet, may Allah bless him and grant him peace, said, "If he is him, then you will not be given power over him."

فَلَنْ then will not

Two pieces fused: front fa- introduces the result of the condition, and the rest flatly negates a future action. The negator is absolute, ruling the outcome out entirely, and it forces the coming verb into the special non-realis ending that goes with denied futures.

From A Night with the Companions

فَإِنَّكَ لَنْ يَزَالَ عَلَيْكَ مِنْ اللَّهِ حَافِظٌ

So indeed, you will always have a guardian from Allah.

لَنْ will not

A particle that negates the future and forces the verb after it into the subjunctive, changing its ending, 'will never...'. It is stronger than ordinary negation; paired with the verb after it here it builds 'will not cease', i.e. 'will always remain'.

From The Verse of the Throne

وَقَالَ لِي لَنْ يَزَالَ عَلَيْكَ مِنَ اللَّهِ حَافِظٌ وَلَا يَقْرَبَكَ شَيْطَانٌ حَتَّى تُصْبِحَ،

He said to me, "A guardian from God will not cease to be upon you, and no devil will come near you until morning."

لَنْ will not

A negation word aimed squarely at the future, 'never will', and it does grammatical work on the verb after it: it pushes that verb into a goal-shape and denies the action will ever happen. It is stronger than an ordinary 'not'.

From The Verse of the Throne

فَإِنَّهُمْ لَنْ يُغْنُوا عَنْكَ مِنَ اللَّهِ شَيْئًا،

For they will never avail you of anything from Allah.

لَنْ will never

This is the emphatic future negator, 'will never'. It denies the verb after it specifically in the future and bends that verb into its subjunctive shape, the changed ending being the grammatical mark this particle leaves. So it both rules out the action for all time to come and reshapes the verb's ending.

From Choosing Good Companions

وَلَكِنَّنِي أَخْشَى أَنْ أُؤْسَرَ فَقَالَ أَنَّكَ لَنْ تُؤْسَرَ

But I fear that I will be taken captive. He said, "You will not be taken captive."

لَنْ will not

This is the particle that negates the future and, in doing so, forces the verb after it into its 'aim' (subjunctive) shape. Its job is a firm 'will never', stronger than an ordinary 'not'. It is the trigger that both denies and reshapes the coming verb.

From A Spy in the Enemy Camp

فيقول إن ربي غضب اليوم غضباً لم يغضب قبله مثله، ولن يغضب بعده مثله، وإنه قد كانت لي دعوة دعوت بها على قومي،

He says, "My Lord was angry today with an anger like none before it, and none like it will be after it, and indeed there was for me a supplication which I invoked against my people,"

وَلَنْ and will not

Two pieces fused: the linking wa- 'and' plus a negation particle that points to the future. Wa- joins this to the previous clause, and the negator denies the coming verb, extending the claim forward in time.

From The Prophet's Intercession

فيقول لهم إن ربي غضب اليوم غضباً لم يغضب قبله مثله، ولن يغضب بعده مثله، وإني كنت كذبت ثلاث كذبات، نفسي نفسي نفسي، اذهبوا إلى غيري،

He will say to them: "My Lord has become angry today with an anger like none before or after. Indeed, I told three lies. Myself, myself, myself! Go to someone else."

وَلَنْ nor after

Here 'wa-' adds a second clause and 'lan' inside it is a forceful future negator: together they extend the denial forward in time, 'and never will...'. This negator specifically rules out the future and reshapes the verb after it.

From The Prophet's Intercession

فيقول إن ربي قد غضب اليوم غضباً لم يغضب قبله مثله، ولن يغضب بعده مثله، وإني قد قتلت نفساً لم أومر بقتلها، نفسي نفسي نفسي، اذهبوا إلى غيري،

He will say: "My Lord has become angry today with an anger like none before or after. Indeed, I killed a person whom I was not commanded to kill. Myself, myself, myself! Go to someone else."

وَلَنْ nor after

'wa-' adds a clause and 'lan' inside it is a strong future negator: together they push the denial forward, 'and never will...'. This negator specifically rules out the future and reshapes the verb after it.

From The Prophet's Intercession

فيقول عيسى إن ربي غضب اليوم غضباً لم يغضب قبله مثله، ولن يغضب بعده مثله ولم يذكر ذنباً،

Then Jesus will say, "My Lord was angry today with an anger like none before it, and none like it will be after it, and he did not mention any sin."

وَلَنْ and will not

'wa-' adds a clause and 'lan' inside it is a strong future negator: together they push the denial forward, 'and never will...'. This negator specifically rules out the future and reshapes the verb after it.
