Sahih al-Bukhari
Virtues and Merits of the Prophet (pbuh) and his Companions
Chapter
Narrated `Urwa:
That the Prophet (ﷺ) gave him one Dinar so as to buy a sheep for him. `Urwa bought two sheep for him with the money. Then he sold one of the sheep for one Dinar, and brought one Dinar and a sheep to the Prophet. On that, the Prophet (ﷺ) invoked Allah to bless him in his deals. So `Urwa used to gain (from any deal) even if he bought dust. (In another narration) `Urwa said, "I heard Allah's Messenger (ﷺ) saying, "There is always goodness in horses till the Day of Resurrection." (The subnarrator added, "I saw 70 horses in `Urwa's house.') (Sufyan said, "The Prophet (ﷺ) asked `Urwa to buy a sheep for him as a sacrifice.")
