Sahih Muslim 2392 d
Abu Huraira reported Allah's Messenger (ﷺ) as saying:
While I was asleep I saw myself drawing water from my tank in order to quench the thirst of the people that there came to me Abu Bakr. He took hold of the leathern bucket from my hand so that he should serve water to the people. He drew two bucketfuls and there was some weakness in his drawing (Allah may forgive him). Then there came Ibn Khattab and he took hold of that, and I did not see a person stronger than he (drawing water) until the people went away with their thirst quenched and the tank filled with water.
حَدَّثَنِي أَحْمَدُ بْنُ عَبْدِ الرَّحْمَنِ بْنِ وَهْبٍ، حَدَّثَنَا عَمِّي عَبْدُ اللَّهِ بْنُ وَهْبٍ، أَخْبَرَنِي 
 عَمْرُو بْنُ الْحَارِثِ، أَنَّ أَبَا يُونُسَ، مَوْلَى أَبِي هُرَيْرَةَ حَدَّثَهُ عَنْ أَبِي هُرَيْرَةَ، عَنْ رَسُولِ اللَّهِ
 صلى الله عليه وسلم قَالَ ‏
"‏ بَيْنَا أَنَا نَائِمٌ أُرِيتُ أَنِّي أَنْزِعُ عَلَى حَوْضِي أَسْقِي النَّاسَ
 فَجَاءَنِي أَبُو بَكْرٍ فَأَخَذَ الدَّلْوَ مِنْ يَدِي لِيُرَوِّحَنِي فَنَزَعَ دَلْوَيْنِ وَفِي نَزْعِهِ ضُعْفٌ وَاللَّهُ يَغْفِرُ
 لَهُ فَجَاءَ ابْنُ الْخَطَّابِ فَأَخَذَ مِنْهُ فَلَمْ أَرَ نَزْعَ رَجُلٍ قَطُّ أَقْوَى مِنْهُ حَتَّى تَوَلَّى النَّاسُ وَالْحَوْضُ
 مَلآنُ يَتَفَجَّرُ ‏"‏ ‏.‏
