Allah's Messenger (ﷺ) said, "Do not withhold the superfluous water, for that will prevent people from grazing their cattle."
Sahih al-Bukhari Book 42, Hadith 3
← Previous Hadith Anas bin Malik said, that once a domestic sheep was milked for Allah's Messenger (ﷺ) while he was in the house of Anas bin Malik. The milk was mixed with water drawn from the well in Anas's house. A tumbler of it was presented to Allah's Messenger (ﷺ) who drank from it. Then Abu Bakr was sitting on his left side and a bedouin on his right side. When the Prophet (ﷺ) removed the tumbler from his mouth, `Umar was afraid that the Prophet (ﷺ) might give it to the bedouin, so he said. "O Allah's Messenger (ﷺ)! Give it to Abu Bakr who is sitting by your side." But the Prophet (ﷺ) gave it to the bedouin, who was to his right and said, "You should start with the one on your right side."

Sahih al-Bukhari Book 42, Hadith 2 Next Hadith → that Allah's Messenger (ﷺ) said, "Do not withhold the superfluous water in order to withhold the superfluous grass."
