Sayyiduna Ibn Abbas (may Allah be pleased with them both), in the explanation of the Divine Words "Do not move your tongue..." says that the Messenger of Allah (peace and blessings be upon him) used to feel great difficulty at the time of the revelation of the Qur'an, and among its (signs) was that, in order to memorize it, he would move his lips. Sayyiduna Ibn Abbas said, "I move my lips just as he used to move them." Sa'id (Sayyiduna Sa'id bin Jubair, who narrates this hadith from Sayyiduna Ibn Abbas, may Allah be pleased with them both) says, "I also move my lips just as I saw Ibn Abbas (may Allah be pleased with them both) move them." Then he moved his lips. (Sayyiduna Ibn Abbas, may Allah be pleased with them both, said:) Then these verses were revealed: "O Muhammad (peace and blessings be upon him), do not move your tongue to hasten to memorize the Qur'an. Its collection and recitation is Our responsibility." (Al-Qiyamah 75:16-17) Sayyiduna Ibn Abbas (may Allah be pleased with them both) says, "That is, to make the Qur'an firm in your heart and to recite it is Our responsibility." Then, when We have recited it, follow its recitation. Sayyiduna Ibn Abbas says (this means) that you should keep listening to it silently. After that, making you understand its meaning is Our responsibility. Then, surely, it is Our responsibility that you recite it (i.e., that you are able to preserve it). Thus, after this, when Jibreel (peace be upon him) would come to you (with revelation), you would listen attentively. When he would leave, the Messenger of Allah (peace and blessings be upon him) would recite that (revelation) just as Jibreel (peace be upon him) had recited it.
