Through the same chain, it is narrated that the Messenger of Allah (peace and blessings be upon him) said to us one day: "I have been told to recite the Qur'an to Ibn al-Khattab (Umar, may Allah be pleased with him)." Then he (peace and blessings be upon him) called him and commanded that he be present whenever the Qur'an was revealed, so that he (peace and blessings be upon him) might recite it to him.
