Sahih Bukhari Volume 9, Book 91, Hadith 7023

حَدَّثَنَا سَعِيدُ بْنُ عُفَيْرٍ، حَدَّثَنِي اللَّيْثُ، قَالَ حَدَّثَنِي عُقَيْلٌ، عَنِ ابْنِ شِهَابٍ، أَخْبَرَنِي سَعِيدٌ، أَنَّ أَبَا هُرَيْرَةَ، أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ بَيْنَا أَنَا نَائِمٌ رَأَيْتُنِي عَلَى قَلِيبٍ وَعَلَيْهَا دَلْوٌ، فَنَزَعْتُ مِنْهَا مَا شَاءَ اللَّهُ، ثُمَّ أَخَذَهَا ابْنُ أَبِي قُحَافَةَ فَنَزَعَ مِنْهَا ذَنُوبًا أَوْ ذَنُوبَيْنِ، وَفِي نَزْعِهِ ضَعْفٌ وَاللَّهُ يَغْفِرُ لَهُ، ثُمَّ اسْتَحَالَتْ غَرْبًا، فَأَخَذَهَا عُمَرُ بْنُ الْخَطَّابِ، فَلَمْ أَرَ عَبْقَرِيًّا مِنَ النَّاسِ يَنْزِعُ نَزْعَ عُمَرَ بْنِ الْخَطَّابِ، حَتَّى ضَرَبَ النَّاسُ بِعَطَنٍ ‏"‏‏

Narrated By Abu Huraira : Allah's Apostle said, "While I was sleeping, I saw myself standing at a well over which there was a bucket. I pulled out from it as many buckets of water as Allah wished, and then Ibn Abi Quhafa (Abu Bakr) took the bucket from me and pulled out one or two full buckets, and there was weakness in his pull... may Allah forgive him. Then the bucket turned into a very large one and 'Umar bin Al-Khattab took it. I have never seen any strong man among the people, drawing water with such strength as 'Umar did, till the people (drank to their satisfaction and) watered their camels to their fill; whereupon the camels sat beside the water."
