"A man from the Ansar disputed with Az-Zubair before the Messenger of Allah (ﷺ) about the canals of Harrah which they used to irrigate the date palms. The Ansari said: 'Let the water pass'. But he refused, So they brought their dispute to the Messenger of Allah (ﷺ). The Messenger of Allah (ﷺ) said to Az-Zubair: 'O Zubair! Irrigate (your land) then let the water pass to you neighbor.' The Ansari became angry and said:'[O Messenger of Allah!] Is this because he is your aunt's son?' The face of the Messenger of Allah (ﷺ) changed color. Then he said: 'O Zubair! Irrigate (your land) and then withhold the water until it reaches the walls.' Az-Zubair said: 'By Allah! I think that this Ayah was revealed about that: But no, by your Lord, they can have no Faith until they make you (O Muhammad) judge in all disputes between them, and find in themselves no resistance against your decisions and accept (them) with full submission.'"
