A man disputed with az-Zubayr about streamlets in the lava plain which was irrigated by them. The Ansari said: Release the water and let it run, but az-Zubayr refused. The Holy Prophet ﷺ said to az-Zubayr: Water (your ground), Zubayr, then let the water run to your neighbour. The Ansari then became angry and said: Messenger of Allah! it is because he is your cousin! Thereupon the face of the Messenger of Allah ﷺ changed colour and he said: Water (your ground), then keep back the water till it returns to the embankment. Az-Zubayr said: By Allah! I think this verse came down about that: "But no , by thy Lord! they can have no (real) faith, until they make thee judge....." (Using translation from Abū Dāʾūd 3637)
اسْتَعْدَى عَلَيَّ رَجُلٌ مِنَ الْأَنْصَارِ رَسُولَ اللَّهِ ﷺ فِي شِرَاجِ الْحَرَّةِ فَقَالَ «يَا زُبَيْرُ اسْقِ ثُمَّ أَرْسَلَ الْمَاءَ إِلَى جَارِكَ» فَقَالَ الْأَنْصَارِيُّ يَا رَسُولَ اللَّهِ إِنْ كَانَ ابْنَ عَمَّتِكَ فَتَلَوَّنَ وَجْهُ رَسُولِ اللَّهِ ﷺ وَقَالَ «يَا زُبَيْرُ اسْقِ ثُمَّ احْبِسِ الْمَاءَ حَتَّى يَبْلُغَ الْجَدْرَ ثُمَّ أَرْسِلْ إِلَى جَارِكَ» فَاسْتَوْعَبَ رَسُولُ اللَّهِ ﷺ لِلزُّبَيْرِ حَقَّهُ فَقَالَ الزُّبَيْرُ إِنِّي لَأَحْسَبُ هَذِهِ الْآيَةَ نَزَلَتْ فِي خُصُومَتِي {فَلَا وَرَبِّكَ لَا يُؤْمِنُونَ حَتَّى يُحَكِّمُوكَ فِيمَا شَجَرَ بَيْنَهُمْ} [النساء 65] الْآيَةَ
