Let the water flow, but he (Zubair) refused to do this and the dispute was brought to Messenger of Allah ﷺ and he said to Zubair: Zubair, water (your date-palms), then let the water flow to your neighbor. The Ansari was enraged and said: Messenger of Allah, (you have given this decision) for he is the son of your father's sister. The face of Allah's Apostle ﷺ underwent a change, and then said: Zubair, water (your date-palms), then hold it until it rises up to the walls. Zubair said: I think, by Allah, that this verse:" Nay, by the Lord, they will not (really) (believe) until they make thee a judge of what is in dispute among them, and find in this no dislike of what thou decidest and submit with full submission" (iv. 65).  

أَنَّ رَجُلاً مِنَ الأَنْصَارِ خَاصَمَ الزُّبَيْرَ عِنْدَ رَسُولِ اللَّهِ ﷺ فِي شِرَاجِ الْحَرَّةِ الَّتِي يَسْقُونَ بِهَا النَّخْلَ فَقَالَ الأَنْصَارِيُّ سَرِّحِ الْمَاءَ يَمُرُّ فَأَبَى عَلَيْهِمْ فَاخْتَصَمُوا عِنْدَ رَسُولِ اللَّهِ ﷺ فَقَالَ رَسُولُ اللَّهِ ﷺ لِلزُّبَيْرِ اسْقِ يَا زُبَيْرُ ثُمَّ أَرْسِلِ الْمَاءَ إِلَى جَارِكَ فَغَضِبَ الأَنْصَارِيُّ فَقَالَ يَا رَسُولَ اللَّهِ أَنْ كَانَ ابْنَ عَمَّتِكَ فَتَلَوَّنَ وَجْهُ نَبِيِّ اللَّهِ ﷺ ثُمَّ قَالَ يَا زُبَيْرُ اسْقِ ثُمَّ احْبِسِ الْمَاءَ حَتَّى يَرْجِعَ إِلَى الْجَدْرِ فَقَالَ الزُّبَيْرُ وَاللَّهِ إِنِّي لأَحْسِبُ هَذِهِ الآيَةَ نَزَلَتْ فِي ذَلِكَ { فَلاَ وَرَبِّكَ لاَ يُؤْمِنُونَ حَتَّى يُحَكِّمُوكَ فِيمَا شَجَرَ بَيْنَهُمْ ثُمَّ لاَ يَجِدُوا فِي أَنْفُسِهِمْ حَرَجًا}
