Az-Zubair told me that he quarreled with an Ansari man who had participated in (the battle of) Badr in front of Allah's Messenger (ﷺ) about a water stream which both of them used for irrigation. Allah's Messenger (ﷺ) said to Az-Zubair, "O Zubair! Irrigate (your garden) first, and then let the water flow to your neighbor." The Ansari became angry and said, "O Allah's Messenger (ﷺ)! Is it because he is your cousin?" On that the complexion of Allah's Messenger (ﷺ) changed (because of anger) and said (to Az-Zubair), "I irrigate (your garden) and then withhold the water till it reaches the walls (surrounding the palms)." So, Allah's Messenger (ﷺ) gave Az-Zubair his full right. Before that Allah's Messenger (ﷺ) had given a generous judgment beneficial for Az-Zubair and the Ansari, but when the Ansan irritated Allah's Messenger (ﷺ) he gave Az-Zubair his full right according to the evident law. Az-Zubair said, "By Allah ! I think the following Verse was revealed concerning that case: "But no by your Lord They can have No faith Until they make you judge In all disputes between them." (4.65)
Sahih al-Bukhari Book 53, Hadith 18
← Previous Hadith Allah's Messenger (ﷺ) said, "There is a Sadaqa to be given for every joint of the human body; and for every day on which the sun rises there is a reward of a Sadaqa (i.e. charitable gift) for the one who establishes justice among people."

Sahih al-Bukhari Book 53, Hadith 17 Next Hadith → My father died and was in debt. I suggested that his creditors take the fruits (i.e. dates) of my garden in lieu of the debt of my father, but they refused the offer, as they thought that it would not cover the full debt. So, I went to the Prophet (ﷺ) and told him about it. He said (to me), "When you pluck the dates and collect them in the Mirbad (i.e. a place where dates are dried), call me (Allah's Messenger (ﷺ))." Finally he came accompanied by Abu Bakr and `Umar and sat on the dates and invoked Allah to bless them. Then he said, "Call your creditors and give them their full rights." So, I paid all my father's creditors in full and yet thirteen extra Wasqs of dates remained, seven of which were 'Ajwa and six were Laun or six of which were Ajwa and seven were Laun. I met Allah's Messenger (ﷺ) at sunset and informed him about it. On that he smiled and said, "Go to Abu Bakr and `Umar and tell them about it." They said, "We perceived that was going to happen, as Allah's Messenger (ﷺ) did what he did."
