Sayyiduna Ibn Abbas (may Allah be pleased with them both) explained regarding Allah Almighty’s statement:“Do not move your tongue with it to hasten it”(Al-Qiyamah: 16), that when Jibreel (peace be upon him) would descend with revelation upon the Messenger of Allah (peace and blessings be upon him), the Messenger of Allah (peace and blessings be upon him) would move his tongue and lips, and this was very hard upon him, which was also apparent from his face. Therefore, Allah Almighty revealed the verse which is in the Surah:“Do not move your tongue with it to hasten it.”It is upon Us to collect it and to recite it, meaning it is Our responsibility to gather the Qur’an in your heart and to make you recite it. Then when We have recited it, follow its recitation, meaning when We reveal the revelation, listen attentively. Then its explanation is also upon Us, meaning it is also Our responsibility to make you explain it to the people with your tongue. It was narrated that after this, whenever Jibreel (peace be upon him) would bring revelation, the Messenger of Allah (peace and blessings be upon him) would remain silent, and when he departed, he would recite it just as Allah Almighty had promised him.
