It is narrated from the family of Abdullah bin Safwan that the Prophet (peace and blessings be upon him) said: "O Safwan! Do you have any weapons?" Safwan said: 'Ariyah (as a loan), or by force? He (peace and blessings be upon him) said: "As a loan." He says: I lent between thirty and forty coats of armour to the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) fought the Battle of Hunayn. When the polytheists were defeated, the coats of armour of Safwan were gathered, and some of the coats were missing. So the Prophet (peace and blessings be upon him) said: "O Safwan! Some of your coats of armour have been lost by us; do we owe you any compensation?" He said: No, O Prophet of Allah (peace and blessings be upon him), because today there is in my heart what was not there that day.
