A man from the Ansar disputed with Zubayr in the presence of the Messenger of Allah ﷺ over the streams of the Harrah which they used to irrigate their date palms. The Ansari said, "Release the water so it may flow through," but Zubayr refused. So they brought their dispute before the Messenger of Allah ﷺ.The Messenger of Allah ﷺ said to Zubayr, "Water your land, Zubayr, then send the water on to your neighbor."The Ansari became angry and said, "Messenger of Allah, is it because he is the son of your aunt?"The face of the Messenger of Allah ﷺ changed color, then he said, "Zubayr, water your land, then hold back the water until it returns to the walls."Zubayr said, "By Allah, I believe this verse was revealed concerning that incident, 'But no, by your Lord, they will not truly believe until they make you judge in their disputes' [Nisa 4:65]."
حدثنا قتيبة حدثنا الليث عن ابن شهاب عن عروة أنه حدثه أن
أن رجلا من الأنصار خاصم الزبير عند رسول الله ﷺ في شراج الحرة التي يسقون بها النخل فقال الأنصاري سرح الماء يمر فأبى عليه فاختصموا عند رسول الله ﷺ فقال رسول الله ﷺ للزبير اسق يا زبير ثم أرسل الماء إلى جارك فغضب الأنصاري فقال يا رسول الله أن كان ابن عمتك فتلون وجه رسول الله ﷺ ثم قال يا زبير اسق ثم احبس الماء حتى يرجع إلى الجدر فقال الزبير والله إني لأحسب نزلت هذه الآية في ذلك {فلا وربك لا يؤمنون حتى يحكموك فيما شجر بينهم}
