It was narrated from 'Urwah that 'Abdullah bin Az-Zubair narrated to him that:

A man among the Ansar disputed with Az-Zubair concerning a stream in Al-Harrah from which they both used to water their date palm trees. The Ansari said: "Let the water flow," but he (Az-Zubair) refused. They brought their dispute to the Messenger of Allah ﷺ. The Messenger of Allah ﷺ said: "Irrigate (your land), O Zubair, then let the water flow to your neighbor." The Ansari became angry and said: "O Messenger of Allah, is it because he is your cousin?" The face of the Messenger of Allah ﷺ changed color (because of anger) and he said: "O Zubair, irrigate (your land) then block the water until it flows back to the walls." Az-Zubair said: "I think that this Verse was revealed concerning this matter: 'But no, by your Lord, they can have no faith.'"

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ، أَنَّهُ حَدَّثَهُ أَنَّ عَبْدَ اللَّهِ بْنَ الزُّبَيْرِ حَدَّثَهُ أَنَّ رَجُلاً مِنَ الأَنْصَارِ خَاصَمَ الزُّبَيْرَ إِلَى رَسُولِ اللَّهِ ﷺ فِي شِرَاجِ الْحَرَّةِ الَّتِي يَسْقُونَ بِهَا النَّخْلَ فَقَالَ الأَنْصَارِيُّ سَرِّحِ الْمَاءَ يَمُرَّ . فَأَبَى عَلَيْهِ فَاخْتَصَمُوا عِنْدَ رَسُولِ اللَّهِ ﷺ فَقَالَ رَسُولُ اللَّهِ ﷺ " اسْقِ يَا زُبَيْرُ ثُمَّ أَرْسِلِ الْمَاءَ إِلَى جَارِكَ " . فَغَضِبَ الأَنْصَارِيُّ فَقَالَ يَا رَسُولَ اللَّهِ أَنْ كَانَ ابْنَ عَمَّتِكَ فَتَلَوَّنَ وَجْهُ رَسُولِ اللَّهِ ﷺ ثُمَّ قَالَ " يَا زُبَيْرُ اسْقِ ثُمَّ احْبِسِ الْمَاءَ حَتَّى يَرْجِعَ إِلَى الْجَدْرِ " . فَقَالَ الزُّبَيْرُ إِنِّي أَحْسَبُ أَنَّ هَذِهِ الآيَةَ نَزَلَتْ فِي ذَلِكَ { فَلاَ وَرَبِّكَ لاَ يُؤْمِنُونَ } الآيَةَ .
