" Move not thy tongue therewith" (Ixxv. 16) that when Gabriel brought revelation to him (the Holy Prophet) he moved his tongue and lips (with a view to committing it to memory instantly). This was something hard for him and it was visible (from his face). Then Allah, the Exalted. revealed this a" Move not thy tongue therewith to make haste (in memorising it). Surely on us rests the collecting of it and the reciting of it" (ixxv. 16), i. e. Verily it rests with Us that We would preserve it in your heart and (enable you) to recite it You would recite it when We would recite it and so follow its recitation, and He (Allah) said:" We revealed it, so listen to it attentively. Verily its exposition rests with Us. i. e. We would make it deliver by your tongue." So when Gabriel came to him (to the Holy Prophet), he kept silence, and when he went away he recited as Allah had promised him.  

فِي قَوْلِهِ ﷻ { لاَ تُحَرِّكْ بِهِ لِسَانَكَ} قَالَ كَانَ النَّبِيُّ ﷺ إِذَا نَزَلَ عَلَيْهِ جِبْرِيلُ بِالْوَحْىِ كَانَ مِمَّا يُحَرِّكُ بِهِ لِسَانَهُ وَشَفَتَيْهِ فَيَشْتَدُّ عَلَيْهِ فَكَانَ ذَلِكَ يُعْرَفُ مِنْهُ فَأَنْزَلَ اللَّهُ تَعَالَى { لاَ تُحَرِّكْ بِهِ لِسَانَكَ لِتَعْجَلَ بِهِ} أَخْذَهُ { إِنَّ عَلَيْنَا جَمْعَهُ وَقُرْآنَهُ} إِنَّ عَلَيْنَا أَنْ نَجْمَعَهُ فِي صَدْرِكَ وَقُرْآنَهُ فَتَقْرَأُهُ { فَإِذَا قَرَأْنَاهُ فَاتَّبِعْ قُرْآنَهُ} قَالَ أَنْزَلْنَاهُ فَاسْتَمِعْ لَهُ { إِنَّ عَلَيْنَا بَيَانَهُ} أَنْ نُبَيِّنَهُ بِلِسَانِكَ فَكَانَ إِذَا أَتَاهُ جِبْرِيلُ أَطْرَقَ فَإِذَا ذَهَبَ قَرَأَهُ كَمَا وَعَدَهُ اللَّهُ  

" Do not move thy tongue there with to make haste," that the Messenger of Allah ﷺ felt it hard and he moved his lips. Ibn 'Abbas said to me (Sa'id b. Jubair): I move them just as the Messenger of Allah ﷺ moved them. Then said Sa'id: I move them just as Ibn 'Abbas moved them, and he moved his lips. Allah, the Exalted, revealed this:" Do not move your tongue therewith to make haste. It is with US that its collection rests and its recital" (al-Qur'an, ixxv. 16). He said: Its preservation in your heart and then your recital. So when We recite it, follow its recital. He said: Listen to it, and be silent and then it rests with Us that you recite it. So when Gabriel came to the Messenger of Allah ﷺ, he listened to him attentively, and when Gabriel went away, the Messenger of Allah ﷺ recited as he (Gabriel) had recited it.  

فِي قَوْلِهِ { لاَ تُحَرِّكْ بِهِ لِسَانَكَ لِتَعْجَلَ بِهِ} قَالَ كَانَ النَّبِيُّ ﷺ يُعَالِجُ مِنَ التَّنْزِيلِ شِدَّةً كَانَ يُحَرِّكُ شَفَتَيْهِ فَقَالَ لِيَ ابْنُ عَبَّاسٍ أَنَا أُحَرِّكُهُمَا كَمَا كَانَ رَسُولُ اللَّهِ ﷺ يُحَرِّكُهُمَا فَقَالَ سَعِيدٌ أَنَا أُحَرِّكُهُمَا كَمَا كَانَ ابْنُ عَبَّاسٍ يُحَرِّكُهُمَا فَحَرَّكَ شَفَتَيْهِ فَأَنْزَلَ اللَّهُ تَعَالَى { لاَ تُحَرِّكْ بِهِ لِسَانَكَ لِتَعْجَلَ بِهِ * إِنَّ عَلَيْنَا جَمْعَهُ وَقُرْآنَهُ} قَالَ جَمْعَهُ فِي صَدْرِكَ ثُمَّ تَقْرَأُهُ { فَإِذَا قَرَأْنَاهُ فَاتَّبِعْ قُرْآنَهُ} قَالَ فَاسْتَمِعْ وَأَنْصِتْ ثُمَّ إِنَّ عَلَيْنَا أَنْ تَقْرَأَهُ قَالَ فَكَانَ رَسُولُ اللَّهِ ﷺ إِذَا أَتَاهُ جِبْرِيلُ اسْتَمَعَ فَإِذَا انْطَلَقَ جِبْرِيلُ قَرَأَهُ النَّبِيُّ ﷺ كَمَا أَقْرَأَهُ
