Musannaf Ibn Abi Shayba 23:177

Muhammad ibn Bishr narrated to us, he said: Ubaydullah ibn Umar narrated to us, he said: Abu Bakr ibn Salim narrated to me, from Salim ibn Abdullah, from his father, that the Messenger of Allah (peace and blessings of Allah be upon him) said: "I saw in a dream as if I were drawing water with a bucket and a pulley from a well. Then Abu Bakr came and drew a bucket or two, and he drew with a weak drawing—may Allah forgive him. Then Umar ibn al-Khattab came and drew water, and it transformed into a large bucket, and I have never seen a master (genius) perform a feat like his, until the people drank their fill and watered their livestock."
