[Machine] That the Messenger of Allah ﷺ was in the mosque while I was praying, and he called me. He said, "I prayed and then I came to you. What prevented you from answering me when I called you? Have you not heard Allah say, 'O you who have believed, respond to Allah and to the Messenger when he calls you to that which gives you life'?" I said, "I will teach you the greatest Surah in the Quran before I leave the mosque." He said, "So I walked with the Messenger of Allah ﷺ until we were about to reach the door of the mosque. I said, 'I forgot,' and I reminded him. I said, 'O Messenger of Allah, you said such and such.' The Messenger of Allah ﷺ said, 'All praise is due to Allah, the Lord of all worlds, the Most Merciful, the Most Compassionate, the Owner of the Day of Judgment. The Surah I was given is the repeating (Surah) and the Great Quran, which I have been given'." 3931 Abu Abdullah Al-Hafiz informed us, Abu Nasr Ahmad ibn Sahl al-Faqih informed me, Salih ibn Muhammad al-Hafiz narrated to us, Ubaidullah ibn Umar al-Jushmi narrated to us, Yahya ibn Said al-Qattan narrated to us, Shu'bah mentioned the hadith in a similar manner, except that he said in his chain of narrators, from `An. And he said, "I called you and you did not answer me." He said, "I was praying." He mentioned the meaning of it
