Sahih Muslim 2393 a
Abdullah b. 'Umar reported Allah's Messenger (ﷺ) as saying:
I saw (in a dream) as if I was drawing water with a leathern bucket on a wooden pulley. There came Abu Bakr and he drew out a bucketful or two and as he drew out, some weakness (was perceived in it) (may Allah, the Exalted and Glorious, forgive him). Then Umar came in order to serve water -and the bucket was changed into a large leather bucket and I did not see such a wonderful man amongst persons (drawing water) and he went on serving water to the people until they were fully satisfied and then went to their resting places.
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَمُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، - وَاللَّفْظُ لأَبِي بَكْرٍ
 - قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ بِشْرٍ، حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ عُمَرَ، حَدَّثَنِي أَبُو بَكْرِ بْنُ سَالِمٍ، عَنْ سَالِمِ،
 بْنِ عَبْدِ اللَّهِ عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏
"‏ أُرِيتُ كَأَنِّي
 أَنْزِعُ بِدَلْوِ بَكْرَةٍ عَلَى قَلِيبٍ فَجَاءَ أَبُو بَكْرٍ فَنَزَعَ ذَنُوبًا أَوْ ذَنُوبَيْنِ فَنَزَعَ نَزْعًا ضَعِيفًا وَاللَّهُ
 تَبَارَكَ وَتَعَالَى يَغْفِرُ لَهُ ثُمَّ جَاءَ عُمَرُ فَاسْتَقَى فَاسْتَحَالَتْ غَرْبًا فَلَمْ أَرَ عَبْقَرِيًّا مِنَ النَّاسِ
 يَفْرِي فَرْيَهُ حَتَّى رَوِيَ النَّاسُ وَضَرَبُوا الْعَطَنَ ‏"‏ ‏.‏
