Sunan an-Nasa'i 4678

It was narrated the Abu Sa'eed Al-Khudri said:"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)
