صحيح مسلم

Abu Huraira reported Allah's Messenger (ﷺ) as saying: While I was asleep I saw myself on a well with a leathern bucket on a pulley. I drew (water) out of that as Allah wished me (to draw). Then the son of Abu Quhafa (Abu Bakr) drew from it one bucketful or two and there was some weakness in drawing that (may Allah forgive him). Then that bucket (changed into a large bucket) and Ibn Khattab drew it. I did not see any strongest man drawing it like 'Umar b. Khattab. He brought out so much water that the camels of the people had enough to drink and then laid down (for rest).
