Sahih al-Bukhari 3648

Ibrahim ibn al-Mundhir narrated to me: Ibn Abi Fudayk narrated to us, from Ibn Abi Dhiʾb, from al-Maqburi, from Abu Hurayra (may Allah be pleased with him), who said: I said, “Messenger of Allah, I hear many things from you, but I forget them.” He said, “Spread out your cloak.” I spread it out, and he scooped into it with his hand. Then he said, “Gather it up.” I gathered it up, and after that I never forgot a report.
