The Messenger of Allah ﷺ would enter it and drink from its pleasant water. When the verse, “You will never attain righteousness until you spend of that which you love; and whatever you spend, Allah is fully aware of it” (Āl ʿImrān 3:92), was revealed, Abu Talhah went to the Messenger of Allah ﷺ and said, “O Messenger of Allah, Allah—Exalted is He—says: ‘You will never attain righteousness until you spend of that which you love; and whatever you spend, Allah is fully aware of it.’ Now, the property I love most is Bayrahāʾ, and I give it in charity for the sake of Allah, hoping for its goodness and the treasure it will become with Allah. So place it, O Messenger of Allah, wherever Allah shows you.” The Messenger of Allah ﷺ replied, “Excellent! That is profitable wealth—profitable wealth indeed. I have heard what you have said, and I think you should distribute it among your close relatives.” Abu Talhah said, “I will do so, O Messenger of Allah,” and he divided it among his relatives and paternal cousins.
