Narrated Hakim ibn Hizam: The Messenger of Allah ﷺ sent with him a dinar to buy a sacrificial animal for him. He bought a sheep for a dinar, sold it for two and then returned and bought a sacrificial animal for a dinar for him and brought the (extra) dinar to the Prophet ﷺ. The Prophet ﷺ gave it as alms (sadaqah) and invoked blessing on him in his trading.

Explanation: Note: (The author has explained the reason for weakness, that is, in his view, Habib’s hearing from Hakim ibn Hizam is not established; therefore, due to the discontinuity (inqita‘) in the chain, this narration is weak.)
