Sahih al-Bukhari Book 62, Hadith 26
Allah's Messenger (ﷺ) said. "While (in a dream), I was standing by a well, drawing water from it. Abu Bakr
and `Umar came to me. Abu Bakr took the bucket (from me) and drew one or two buckets of water,
and there was some weakness in his drawing. May Allah forgive him. Then Ibn Al-Khattab took the
bucket from Abu Bakr, and the bucket turned into a very large one in his hands. I had never seen such
a mighty person amongst the people as him in performing such hard work. He drew so much water
that the people drank to their satisfaction and watered their camels." (Wahab, a sub-narrator said, "till
their camels drank and knelt down.")
The Prophet (ﷺ) once climbed the mountain of Uhud with Abu Bakr, `Umar and `Uthman. The mountain shook with them. The Prophet (ﷺ) said (to the mountain), "Be firm, O Uhud! For on you there are no more than a Prophet, a Siddiq and two martyrs.
While I was standing amongst the people who were invoking Allah for `Umar bin Al-Khattab who was lying (dead) on his bed, a man behind me rested his elbows on my shoulder and said, "(O `Umar!) May Allah bestow His Mercy on you. I always hoped that Allah will keep you with your two companions, for I often heard Allah's Messenger (ﷺ) saying, "I, Abu Bakr and `Umar were (somewhere). I, Abu Bakr and `Umar did (something). I, Abu Bakr and `Umar set out.' So I hoped that Allah will keep you with both of them." I turned back to see that the speaker was `Ali bin Abi Talib.
