Narrated from Sayyiduna Abdullah bin Zubair (may Allah be pleased with them both) that there was a dispute between Sayyiduna Zubair (may Allah be pleased with him) and an Ansari regarding a stream in Harrah, from which they used to irrigate their date palms. The Ansari (may Allah be pleased with him) said to Sayyiduna Zubair (may Allah be pleased with him): Leave the water for my date palms, but he refused to do so. The Ansari took the case to the Messenger of Allah (peace and blessings of Allah be upon him). The Messenger of Allah (peace and blessings of Allah be upon him) said: O Zubair! First irrigate (your land) and then leave the water for your neighbor. But this decision angered the Ansari, and he said: You have given this decision because he is your aunt’s son. Upon hearing this, the face of the Messenger of Allah (peace and blessings of Allah be upon him) changed, and then he said: O Zubair! Now withhold the water until it reaches the embankment, then let it flow ahead. Sayyiduna Zubair (may Allah be pleased with him) says: By Allah! I think this verse was revealed about this matter: {فَلَاوَرَبِّکَ لَایُؤْمِنُوْنَ حَتّٰییُحَکِّمُوْکَ فِیْمَا شَجَرَ بَیْنَہُمْ ثُمَّ لَا یَجِدُوْا فِیْ اَنْفُسِھِمْ حَرَجًا مِّمَّا قَضَیْتَ وَیُسَلِّمُوْا تَسْلِیْمًا} … But no, by your Lord, they will not (truly) believe until they make you (O Muhammad) judge in all disputes between them, and then find in themselves no resistance against your decisions, and accept them with full submission. (Surah An-Nisa: 65)
