Narrated Urwa bin Az-Zubair:

Az-Zubair told me that he quarrelled with an Ansari man who had participated in (the battle of) Badr in front of Allah's Apostle about a water stream which both of them used for irrigation. Allah's Apostle ﷺ said to Az-Zubair, "O Zubair! Irrigate (your garden) first, and then let the water flow to your neighbor." The Ansari became angry and said, "O Allah's Apostle! Is it because he is your cousin?" On that the complexion of Allah's Apostle changed (because of anger) and said (to Az-Zubair), "I irrigate (your garden) and then with-hold the water till it reaches the walls (surrounding the palms)." So, Allah's Apostle gave Az-Zubair his full right. Before that Allah's Apostle had given a generous judgment beneficial for Az-Zubair and the Ansari, but when the Ansan irritated Allah's Apostle he gave Az-Zubair his full right according to the evident law. Az-Zubair said, "By Allah ! I think the following Verse was revealed concerning that case: "But no by your Lord They can have No faith Until they make you judge In all disputes between them." (4.65)

حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي عُرْوَةُ بْنُ الزُّبَيْرِ، أَنَّ الزُّبَيْرَ، كَانَ يُحَدِّثُ أَنَّهُ خَاصَمَ رَجُلاً مِنَ الأَنْصَارِ قَدْ شَهِدَ بَدْرًا إِلَى رَسُولِ اللَّهِ ﷺ فِي شِرَاجٍ مِنَ الْحَرَّةِ كَانَا يَسْقِيَانِ بِهِ كِلاَهُمَا فَقَالَ رَسُولُ اللَّهِ ﷺ لِلزُّبَيْرِ " اسْقِ يَا زُبَيْرُ ثُمَّ أَرْسِلْ إِلَى جَارِكَ ". فَغَضِبَ الأَنْصَارِيُّ فَقَالَ يَا رَسُولَ اللَّهِ آنْ كَانَ ابْنَ عَمَّتِكَ فَتَلَوَّنَ وَجْهُ رَسُولِ اللَّهِ ﷺ ثُمَّ قَالَ " اسْقِ ثُمَّ احْبِسْ حَتَّى يَبْلُغَ الْجَدْرَ ". فَاسْتَوْعَى رَسُولُ اللَّهِ ﷺ حِينَئِذٍ حَقَّهُ لِلزُّبَيْرِ، وَكَانَ رَسُولُ اللَّهِ ﷺ قَبْلَ ذَلِكَ أَشَارَ عَلَى الزُّبَيْرِ بِرَأْىٍ سَعَةٍ لَهُ وَلِلأَنْصَارِيِّ، فَلَمَّا أَحْفَظَ الأَنْصَارِيُّ رَسُولَ اللَّهِ ﷺ اسْتَوْعَى لِلزُّبَيْرِ حَقَّهُ فِي صَرِيحِ الْحُكْمِ. قَالَ عُرْوَةُ قَالَ الزُّبَيْرُ وَاللَّهِ مَا أَحْسِبُ هَذِهِ الآيَةَ نَزَلَتْ إِلاَّ فِي ذَلِكَ {فَلاَ وَرَبِّكَ لاَ يُؤْمِنُونَ حَتَّى يُحَكِّمُوكَ فِيمَا شَجَرَ بَيْنَهُمْ} الآيَةَ.
