Ibn ‘Abbās (may Allah be pleased with him) commented about the verse: {Move not your tongue with it, [O Muhammad], to hasten with recitation of the Qur'an} [Sūrat al-Qiyāmah: 16], saying: "The Prophet (may Allah's peace and blessings be upon him) used to experience hardship while the revelation was being sent down upon him, and he used to move his lips (quickly) with what was being revealed to him." Ibn ‘Abbās moved his lips saying: "I am moving my lips in front of you as the Messenger of Allah (may Allah's peace and blessings be upon him) used to move his." Sa‘īd (the sub-narrator) also moved his lips saying: "I am moving my lips just as I saw Ibn ‘Abbās moving his." Ibn ‘Abbās added: "So Allah revealed the following verses: {Move not your tongue with it, [O Muhammad], to hasten with recitation of the Qur'an. Indeed, upon Us is its collection [in your heart] and [to make possible] its recitation.} [Sūrat al-Qiyāmah: 16-17] which means that Allah will make him (the Prophet) remember the portion of the Qur'an which was revealed to him at that time by heart and recite it. Then the verse that followed these two was: {So when We have recited it [through Jibrīl], then follow its recitation} [Sūrat al-Qiyāmah: 18] It means ''listen to it and be silent. Then, it is (for Allah) to make you recite it." Afterwards, the Messenger of Allah (may Allah's peace and blessings be upon him) used to listen to Jibrīl whenever he came to him, and after his departure he used to recite it just as Jibrīl taught him to recite it."
