It was narrated from Az-Zubair bin Al-'Awwam that: He disputed with a man among Ansar who had been present at Badr with the Messenger of Allah [SAW], 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. The Messenger of Allah [SAW] 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 [SAW] changed color (because of anger) and he said: O Zubair! Irrigate (your land) then block the water, until it flows back to the walls. So the Messenger of Allah [SAW] allowed Az-Zubair to take his rights in full, although before that he had suggested to Az-Zubair a middle way that benefited both him and the Ansari. But when the Ansari made the Messenger of Allah [SAW] angry, he gave Az-Zubair his rights in full, as stated clearly in his ruling. Az-Zubair said: I think that this Verse was revealed concerning this matter: 'But no, by your Lord, they can have no faith, until they make you (O Muhammad) judge in all disputes between them.'
