Hadith 8:190
Umayya b. Safwan quoted his father as saying that at the battle of Hunain the Prophet borrowed his coats of mail and he asked, “Are you taking them by force, Muhammad ?” to which he replied, “No, it is a loan with a guarantee of their return.'’ Abu Dawud transmitted it.
وَعَن أُميَّة بن صَفْوَان عَنْ أَبِيهِ: أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ اسْتَعَارَ مِنْهُ أَدْرَاعَهُ يَوْمَ حُنَيْنٍ فَقَالَ: أَغَصْبًا يَا مُحَمَّدَ؟ قَالَ: «بَلْ عَارِيَةً مَضْمُونَةً» . رَوَاهُ أَبُو دَاوُد
