Sahih al-Bukhari Book 61, Hadith 146
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.")
I heard the Prophet (ﷺ) saying, "A group of people amongst my followers will remain obedient to Allah's orders and they will not be harmed by anyone who will not help them or who will oppose them, till Allah's Order (the Last Day) comes upon them while they are still on the right path."
Allah's Messenger (ﷺ) said, "There is always goodness in horses till the Day of Resurrection. "
