AbdulAziz ibn Rufay' narrated on the authority of some people from the descendants of Abdullah ibn Safwan who reported the Messenger of Allah ﷺ 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 Messenger of Allah ﷺ fought the battle of Hunayn. When the polytheists were defeated, the coats of mail of Safwan were collected. Some of them were lost. The Messenger of Allah ﷺ said to Safwan: We have lost some coats of mail from your coats of mail. Should we pay compensation to you? He replied: No. Messenger of Allah, for I have in my heart today what I did not have that day. Abu Dawud said: He lent him before embracing Islam. Then he embraced Islam. (Using translation from Abū Dāʾūd 3563)   

أَنَّ رَسُولَ اللهِ ﷺ قَالَ يَا صَفْوَانُ هَلْ عِنْدَكَ سِلَاحٌ؟ قَالَ عَارِيَةً أَمْ غَصْبًا؟ قَالَ بَلْ عَارِيَةٌ قَالَ فَأَعَارَهُ مَا بَيْنَ الثَّلَاثِينَ إِلَى الْأَرْبَعِينَ دِرْعًا وَغَزَا رَسُولُ اللهِ ﷺ حُنَيْنًا فَلَمَّا هُزِمَ الْمُشْرِكُونَ جُمِعَتْ دُرُوعُ صَفْوَانَ فَفُقِدَ مِنْهَا أَدْرَاعًا فَقَالَ النَّبِيُّ ﷺ لِصَفْوَانَ إِنَّا قَدْ فَقَدْنَا مِنْ أَدْرَاعِكَ أَدْرَاعًا فَهَلْ نَغْرَمُ لَكَ؟ قَالَ لَا يَا رَسُولَ اللهِ لِأَنَّ فِي قَلْبِي الْيَوْمَ مَا لَمْ يَكُنْ يَوْمَئِذٍ
