I have come from Koofah, O Ameer al-Mu'mineen, and I left behind in it a man who dictates the Mushaf From memory. ‘Umar got exceedingly angry and said: Who is he, woe to you? He said: 'Abdullah bin Mas'ood. ‘Umar began to calm down, and went back to normal, then he said: Woe to you, I do not know of anyone who is more qualified to do that than him, and I will tell you about that. The Messenger of Allah ﷺ used to stay up at night talking with Abu Bakr ؓ discussing some affairs of the Muslims. He stayed up talking with him one night, and I was with him. The Messenger of Allah ﷺ went out, and we went out with him, and we saw a man standing and praying in the mosque. The Messenger of Allah ﷺ listened to his recitation, and as soon as we recognised him the Messenger of Allah ﷺ said: ʿWhoever would like to recite the Qur'an fresh as it was revealed, let him recite it according to the recitation of Ibn Umm 'Abd.ʿ Then the same man sat and offered supplication (du'a') and the Messenger of Allah ﷺ started saying to him: ʿAsk, you will be given;ask, you will be given.” ‘Umar said: By Allah, I shall go to him tomorrow and tell hirm the glad tidings. I went to him the next morning to tell him the glad tidings, and I found that Abu Bakr had beaten me to it and given him the glad tidings. By Allah, I never competed with him to do good but he beat me to it. (Using translation from Aḥmad 175)
