Abu Dawud Book 17, Hadith Number 3556.
Chapter : Not known.
Narated By Some people : AbdulAziz ibn Rufay’ narrated on the authority of some people from the descendants of Abdullah ibn Safwan who reported the Apostle of Allah (PBUH) as saying: Have you weapons, Safwan? He asked: On loan or by force? He replied: No, but on loan. So he lent him coats of mail numbering between thirty and forty! The Apostle of Allah (PBUH) fought the battle of Hunayn. When the polytheists were defeated, the coats of mail of Safwan were collected. Some of them were lost. The Apostle of Allah (PBUH) said to Safwan: We have lost some coats of mail from your coats of mail. Should we pay compensation to you? He replied: No. Apostle of Allah, for I have in my heart today what I did not have that day.
