Narrated by Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Among the Children of Israel, there was a man who bought land from another man. The buyer found a pot of gold in that land. He said to the seller: Take your gold, for I bought the land from you, not the gold. But the seller said: I sold the land and everything in it to you. So they both took their case to a man for judgment. He asked: Do you have children? One of them said: He has a son, and the other said: She has a daughter. He said: Marry the boy to the girl, spend the gold on them, and give some amount in charity.

Narrated from Sayyiduna ‘Urwah bin Abi Ja‘d Barqī (may Allah be pleased with him) that news reached the Noble Prophet (peace and blessings be upon him) that a caravan with merchandise had arrived. So the Prophet (peace and blessings be upon him) gave me one dinar and said:“‘Urwah! Go to the caravan and buy a goat for us.”So I went to the caravan and bargained with the owner of the goats and bought two goats for one dinar. As I was bringing them back, I met a man on the way, made a deal with him, and sold him one goat for one dinar. Thus, I returned with one goat and one dinar and said:“O Messenger of Allah! Here is your dinar and here is your goat.”The Prophet (peace and blessings be upon him) asked:“How did you make this deal?”I told him the whole story. Then the Prophet (peace and blessings be upon him) said:“O Allah! Bless him in his trade.”This supplication was accepted to such an extent that I would stand at the place of Kunāsah in Kufa and, before reaching home, would earn a profit of forty thousand.
