Narrated Some people:

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.

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا جَرِيرٌ، عَنْ عَبْدِ الْعَزِيزِ بْنِ رُفَيْعٍ، عَنْ أُنَاسٍ، مِنْ آلِ عَبْدِ اللَّهِ بْنِ صَفْوَانَ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " يَا صَفْوَانُ هَلْ عِنْدَكَ مِنْ سِلاَحٍ " . قَالَ عَارِيَةً أَمْ غَصْبًا قَالَ " لاَ بَلْ عَارِيَةً " . فَأَعَارَهُ مَا بَيْنَ الثَّلاَثِينَ إِلَى الأَرْبَعِينَ دِرْعًا وَغَزَا رَسُولُ اللَّهِ ﷺ حُنَيْنًا فَلَمَّا هُزِمَ الْمُشْرِكُونَ جُمِعَتْ دُرُوعُ صَفْوَانَ فَفَقَدَ مِنْهَا أَدْرَاعًا فَقَالَ رَسُولُ اللَّهِ ﷺ لِصَفْوَانَ " إِنَّا قَدْ فَقَدْنَا مِنْ أَدْرَاعِكَ أَدْرَاعًا فَهَلْ نَغْرَمُ لَكَ " . قَالَ لاَ يَا رَسُولَ اللَّهِ لأَنَّ فِي قَلْبِي الْيَوْمَ مَا لَمْ يَكُنْ يَوْمَئِذٍ . قَالَ أَبُو دَاوُدَ وَكَانَ أَعَارَهُ قَبْلَ أَنْ يُسْلِمَ ثُمَّ أَسْلَمَ .
