Umayya b. Safwan quoted his father as saying that at the battle of Hunain the Prophet borrowed his coats of mail and he asked, “Are you taking them by force, Muhammad ?” to which he replied, “No, it is a loan with a guarantee of their return.'’
Abu Umama told of hearing God's Messenger say, “A loan must be paid back, a minha* must be returned, a debt must be discharged, and one who stands surety is held responsible.”
Tirmidhi and Abu Dawud transmitted it.
*This may be a she camel lent for a time for milking, but it can be used of other things which are lent for some specific purpose.
Al-Hasan on Samura’s authority reported the Prophet as saying, “When any of you comes upon animals whose owner is among them he must ask his permission; if not he must call three times and if anyone answers him he must ask his permission; but if no one answers him he may draw some milk and drink, but not carry any away.”
