Move not your tongue concerning the Quran to make haste therewith. Verily, it is for us to collect it and give to you the ability to recite it. And when We have recited it to you through Jibrael, then follow its recital. Thereafter, it is for us to make it clear (to you). (Surah Al-Qiyamah: 16-19)
In the above verse, Allah سبحانہ وتعالی commands the Holy Prophet صلی اللہ علیہ وسلم in the usual affectionate manner. Explaining the circumstances of revelation, Sayyidina Abdullah bin Abbas رضی اللہ عنہ narrates that when revelation used to come to the Holy Prophet صلی اللہ علیہ وسلم, he would try to repeat the words immediately upon hearing them, fearing that he would forget them. In this manner, the strain would be multiplied. Advising him not to exert himself so much, Allah said, “Do not move your tongue with the Quran to hasten it. Verily, it is Our responsibility to collect it (in your heart) and to make you recite it. So when We have recited it follow its recitation.” Allah commanded the Holy Prophet صلی اللہ علیہ وسلم to first listen attentively to the recitation of the Quran and then to repeat the words.
