صحيح البخاري

Narrated `Abdullah:

Allah's Messenger (ﷺ) said, "I saw (in a dream) the people assembled in a gathering, and then Abu Bakr got up and drew one or two buckets of water (from a well) but there was weakness in his drawing. May Allah forgive him. Then `Umar took the bucket and in his hands it turned into a very large bucket. I had never seen anyone amongst: the people who could draw the water as strongly as `Umar till all the people drank their fill and watered their camels that knelt down there.
