قَوْلُهُ تَعَالَى: {فَلَا وَرَبِّكَ لَا يُؤْمِنُونَ حَتَّى يُحَكِّمُوكَ فِيمَا شَجَرَ بَيْنَهُمْ} [النساء: 65]
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)
أَنَّ رَجُلًا خَاصَمَ الزُّبَيْرَ عِنْدَ رَسُولِ اللهِ ﷺ فِي شِرَاجِ الْحَرَّةِ الَّتِي كَانُوا يَسْقُونَ بِهَا النَّخْلَ فَقَالَ الْأَنْصَارِيُّ سَرِّحِ الْمَاءَ يَمُرُّ فَأَبَى عَلَيْهِمْ فَاخْتَصَمُوا عِنْدَ رَسُولِ اللهِ ﷺ فَقَالَ رَسُولُ اللهِ ﷺ لِلزُّبَيْرِ اسْقِ يَا زُبَيْرُ ثُمَّ أَرْسِلْ إِلَى جَارِكَ فَغَضِبَ الْأَنْصَارِيُّ فَقَالَ يَا رَسُولَ اللهِ أَنْ كَانَ ابْنَ عَمَّتِكَ فَتَلَوَّنَ وَجْهُ رَسُولِ اللهِ ﷺ ثُمَّ قَالَ «يَا زُبَيْرُ اسْقِ ثُمَّ احْبِسِ الْمَاءَ حَتَّى يَرْجِعَ إِلَى الْجَدْرِ» قَالَ الزُّبَيْرُ وَاللهِ إِنِّي أَحْسِبُ هَذِهِ الْآيَةَ نَزَلَتْ فِي ذَلِكَ {فَلَا وَرَبِّكَ لَا يُؤْمِنُونَ} [النساء 65]
