"At the time of the Messenger of Allah, a man suffered loss of some fruit that he had purchased, and his debts increased. "The Messenger of Allah said: 'Give him charity.' So the people gave him charity, but that was not enough to pay off his debts. 'The Messenger of Allah said: 'Take what you find, but you have no right to more than that."' (meaning his creditors).

the Messenger of Allah ruled that if a man found (his goods) in the possession of a man who was not guilty, then if he wished he could give the man what he had paid for it, or if he wished he could go after the one who had stolen it. Abu Bakr and 'Umar passed similar judgments.

there was the governor of Al-Yamamah, and Marwan wrote to him saying that Mu'awiyah had written to him, saying that any man who had something stolen from him had more right to it wherever he found it. Then Marwan wrote saying that to me (Usaid). I wrote to Marwan saying that the Prophet had ruled that if the one who bought it from the one who stole it is ot guilty of anything (and did not realize that it was stolen goods), then the owner has the choice: If he wishes, he may buy it from the one who bought it from the thief, or if he wishes he may go after the thief. Abu Bakr, 'Umar and 'Uthman also passed judgment along these lines. Marwan sent my letter to Mu'awiyah, and Mu'awiyah wrote to Marwan (saying): 'Neither you nor Usaid are in a position to tell me what to do, rather I am the one who tells you what to do because I am superior in rank to you, so do what I tell you.' Marwan sent the letter of Mu'awiyah to me, and I said: I will not judge according to Mu'awiyah's opinion as long as I am the governor."'

"We were with the Prophet at a funeral, and he said: 'I there anyone from banu so and so here? He said this three times. Then a man stood up, and he said to him: 'What kept you form answering the first two times? I am not going to say anything but good to you, so and so (mentioning the name of a man from among them) has died and he is being detained (from entering Paradise) because of his debt."'
