a man from among the Ansar had a dispute with Zubair in the presence of the Messenger of Allah ﷺ concerning the streams of the Harrah with which he irrigated his palm trees. The Ansari said: “Let the water flow,” but he refused. So they referred their dispute to the Messenger of Allah ﷺ. The Messenger of Allah ﷺ said: “Irrigate (your trees) O Zubair, then let the water flow to your neighbor.” The Ansari became angry and said: “O Messenger of Allah ﷺ, is it because he is your cousin (son of your paternal aunt)?” The expression of the Messenger of Allah ﷺ changed, then he said: “O Zubair, irrigate (your trees) then retain the water until it reaches the walls.” Zubair said: “I think this Verse was revealed concerning that: “But no, by your Lord, they make you (O Muhammad) judge in all disputes between them, and find in themselves no resistance against your decisions, and accept (them) with full submission [1].'” (Sahih) [1] An-Nisa 4.65  

أَنَّ رَجُلاً مِنَ الأَنْصَارِ خَاصَمَ الزُّبَيْرَ عِنْدَ رَسُولِ اللَّهِ ﷺ فِي شِرَاجِ الْحَرَّةِ الَّتِي يَسْقُونَ بِهَا النَّخْلَ فَقَالَ الأَنْصَارِيُّ سَرِّحِ الْمَاءَ يَمُرَّ فَأَبَى عَلَيْهِ فَاخْتَصَمَا 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 قَالَ فَقَالَ الزُّبَيْرُ وَاللَّهِ إِنِّي لأَحْسَبُ هَذِهِ الآيَةَ أُنْزِلَتْ فِي ذَلِكَ {فَلاَ وَرَبِّكَ لاَ يُؤْمِنُونَ حَتَّى يُحَكِّمُوكَ فِيمَا شَجَرَ بَيْنَهُمْ ثُمَّ لاَ يَجِدُوا فِي أَنْفُسِهِمْ حَرَجًا مِمَّا قَضَيْتَ وَيُسَلِّمُوا تَسْلِيمًا}  

“The Messenger of Allah ﷺ ruled concerning the stream of Mahzur that the higher ground took precedence over the lower, so the higher ground should be irrigated until the water reached the ankles, then it should be released to those who were lower.  

قَضَى رَسُولُ اللَّهِ ﷺ فِي سَيْلِ مَهْزُورٍ الأَعْلَى فَوْقَ الأَسْفَلِ يَسْقِي الأَعْلَى إِلَى الْكَعْبَيْنِ ثُمَّ يُرْسِلُ إِلَى مَنْ هُوَ أَسْفَلُ مِنْهُ  

the Messenger of Allah ﷺ ruled concerning the stream of Mahzur that the water should be retained until it reached the ankles, then released.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَضَى فِي سَيْلِ مَهْزُورٍ أَنْ يُمْسِكَ حَتَّى يَبْلُغَ الْكَعْبَيْنِ ثُمَّ يُرْسِلَ الْمَاءَ  

the Messenger of Allah ﷺ ruled concerning the irrigation of palm trees from streams, that the higher ground should be irrigated before the lower, and that the water should be allowed to reach the ankles, then released to flow the nearest lower ground, and so on, until all the fields were watered or until the water ran out.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَضَى فِي شُرْبِ النَّخْلِ مِنَ السَّيْلِ أَنَّ الأَعْلَى فَالأَعْلَى يَشْرَبُ قَبْلَ الأَسْفَلِ وَيُتْرَكُ الْمَاءُ إِلَى الْكَعْبَيْنِ ثُمَّ يُرْسَلُ الْمَاءُ إِلَى الأَسْفَلِ الَّذِي يَلِيهِ وَكَذَلِكَ حَتَّى تَنْقَضِيَ الْحَوَائِطُ أَوْ يَفْنَى الْمَاءُ
