Sahih al-Bukhari 2361
Narrated `Urwa:
When a man from the Ansar quarreled with Az-Zubair, the Prophet (ﷺ) said, "O Zubair! Irrigate (your 
land) first and then let the water flow (to the land of the others)." "On that the Ansari said, (to the 
Prophet), "It is because he is your aunt's son." On that the Prophet (ﷺ) said, "O Zubair! Irrigate till the 
water reaches the walls between the pits around the trees and then stop (i.e. let the water go to the 
other's land)." I think the following verse was revealed concerning this event: "But no, by your Lord 
They can have No faith Until they make you judge In all disputes between them." (4.65)
حَدَّثَنَا عَبْدَانُ، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، قَالَ خَاصَمَ الزُّبَيْرَ رَجُلٌ مِنَ الأَنْصَارِ، فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ يَا زُبَيْرُ اسْقِ ثُمَّ أَرْسِلْ ‏"‏‏.‏ فَقَالَ الأَنْصَارِيُّ إِنَّهُ ابْنُ عَمَّتِكَ‏.‏ فَقَالَ عَلَيْهِ السَّلاَمُ ‏"‏ اسْقِ يَا زُبَيْرُ، ثُمَّ يَبْلُغُ الْمَاءُ الْجَدْرَ، ثُمَّ أَمْسِكْ ‏"‏‏.‏ فَقَالَ الزُّبَيْرُ فَأَحْسِبُ هَذِهِ الآيَةَ نَزَلَتْ فِي ذَلِكَ ‏{‏َلاَ وَرَبِّكَ لاَ يُؤْمِنُونَ حَتَّى يُحَكِّمُوكَ فِيمَا شَجَرَ بَيْنَهُمْ‏}‏‏.‏ قَالَ مُحَمَّدُ بْنُ الْعَبَّاسِ قَالَ أَبُو عَبْدِ اللَّهِ لَيْسَ أَحَدٌ يَذْكُرُ عُرْوَةَ عَنْ عَبْدِ اللَّهِ، إِلاَّ اللَّيْثُ فَقَطْ‏.‏
