Volume 9, Book 87, Number 149:
Narrated Abu Huraira:
Allah’s Apostle said, “While I was sleeping, I saw myself standing over a tank (well) giving water to
the people to drink. Then Abu Bakr came to me and took the bucket from me in order to relieve me
and he pulled out one or two full buckets, and there was weakness in his pulling –may Allah for –
give him. Then Ibn Al-Khattab took it from him and went on drawing water till the people left (after
being satisfied) while the tank was over flowing with water.”
