Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with them both) said that a man of the Ansar disputed with Sayyiduna al-Zubayr (may Allah be pleased with him) over the water channel of the Harrah, with which they watered the date palms. Then they put their dispute before the Messenger of Allah (peace and blessings be upon him). The Ansari said: "Let the water pass on," but Sayyiduna al-Zubayr (may Allah be pleased with him) refused. The two of them came to the Messenger of Allah (peace and blessings be upon him). The Messenger of Allah (peace and blessings be upon him) said: "O Zubayr! Water (your garden) first, then let it go to your neighbour." The Ansari became angry and said: "O Messenger of Allah (peace and blessings be upon him)! Is it because Zubayr is the son of your paternal aunt?" The colour of the face of the Messenger of Allah (peace and blessings be upon him) changed. He (peace and blessings be upon him) said: "O Zubayr! Water (your garden), then hold back the water until it rises to the walls." Sayyiduna al-Zubayr (may Allah be pleased with him) said: "By Allah! I think this verse was revealed concerning that: 'But no, by your Lord, they will not believe until they make you judge concerning their disputes' [Surah al-Nisa: 65]."
