Ya’la bin Umayyah narrates from his father, who says that the Messenger of Allah (peace and blessings be upon him) said to me:“When my messengers come to you, give them thirty coats of mail and thirty camels.”I said: O Messenger of Allah! If (these things that I am) lending are destroyed, will their value be guaranteed or not? The Prophet (peace and blessings be upon him) said:“If these things remain as they are, then their return is guaranteed, and in case of destruction, there will be no responsibility.”
