سنن النسائي

It was narrated from 'Urwah that 'Abdullah bin Az-Zubair narrated to him that: A man among the Ansar disputed with Az-Zubair 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. They brought their dispute to the Messenger of Allah (ﷺ) [SAW]. The Messenger of Allah (ﷺ) [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 (ﷺ) [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." Az-Zubair said: "I think that this Verse was revealed concerning this matter: 'But no, by your Lord, they can have no faith.'"
