Concerning the saying of Allah, the Mighty and Sublime: "Move not your tongue concerning to make haste therewith. It is for Us to collect it and to give you the ability to recite it- "The Prophet ﷺ used to suffer a great deal of hardship when the Revelation came to him, and he used to move his lips. Allah said: Move not your tongue concerning to make haste therewith. It is for Us to collect it and to give you the ability to recite it." He said: " (This means) He will gather it in your heart, then you will recite it," And when We have recited it to you, then follow the recitation. He said: "So listen to it and remain silent. So when Jibril came to him, the Messenger of Allah ﷺ listened, and when he left, he would recite it as he had taught him."  

فِي قَوْلِهِ ﷻ { لاَ تُحَرِّكْ بِهِ لِسَانَكَ لِتَعْجَلَ بِهِ * إِنَّ عَلَيْنَا جَمْعَهُ وَقُرْآنَهُ } قَالَ كَانَ النَّبِيُّ ﷺ يُعَالِجُ مِنَ التَّنْزِيلِ شِدَّةً وَكَانَ يُحَرِّكُ شَفَتَيْهِ قَالَ اللَّهُ ﷻ { لاَ تُحَرِّكْ بِهِ لِسَانَكَ لِتَعْجَلَ بِهِ * إِنَّ عَلَيْنَا جَمْعَهُ وَقُرْآنَهُ } قَالَ جَمْعَهُ فِي صَدْرِكَ ثُمَّ تَقْرَأَهُ { فَإِذَا قَرَأْنَاهُ فَاتَّبِعْ قُرْآنَهُ } قَالَ فَاسْتَمِعْ لَهُ وَأَنْصِتْ فَكَانَ رَسُولُ اللَّهِ ﷺ إِذَا أَتَاهُ جِبْرِيلُ اسْتَمَعَ فَإِذَا انْطَلَقَ قَرَأَهُ كَمَا أَقْرَأَهُ  

كَانَ النَّبِيُّ ﷺ إِذَا نَزَلَ الْقُرْآنُ عَلَيْهِ يَعْجَلُ بِقِرَاءَتِهِ لِيَحْفَظَهُ فَأَنْزَلَ اللهُ ﷻ {لَا تُحَرِّكْ بِهِ لِسَانَكَ} [القيامة 16] إِلَى قَوْلِهِ {وَقُرْآنَهُ} [القيامة 17]
