Ibn Abbas (RA) reported with regard to the words:" Do not move thy tongue there with to make haste," that the Apostle of Allah ﷺ felt it hard and he moved his lips. Ibn Abbas said to me (Said bin Jubair): I move them just as the Messenger of Allah ﷺ moved them. Then said Said: 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-Quran, 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 (علیہ السلام) came to the Messenger of Allah ﷺ , he listened to him attentively, and when Gabriel (علیہ السلام) went away, the Apostle of Allah ﷺ recited as he ( Gabriel (علیہ السلام)) had recited it.
