That the Messenger of Allah ﷺ said: "Whomever you find stealing from the spoils of war while in the path of Allah, then burn his belongings." Salih (one of the narrators) said: "I entered upon Maslamah and with him was Salim bin 'Abdullah. There was a man there who had stolen from the spoils of war, so Salim narrated this Hadith. So he ordered accordingly, and his belongings were burnt. There was a Mushaf in his belongings, so Salim said: 'Sell this and give its proceeds as charity.'"  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَنْ وَجَدْتُمُوهُ غَلَّ فِي سَبِيلِ اللَّهِ فَاحْرِقُوا مَتَاعَهُ قَالَ صَالِحٌ فَدَخَلْتُ عَلَى مَسْلَمَةَ وَمَعَهُ سَالِمُ بْنُ عَبْدِ اللَّهِ فَوَجَدَ رَجُلاً قَدْ غَلَّ فَحَدَّثَ سَالِمٌ بِهَذَا الْحَدِيثِ فَأَمَرَ بِهِ فَأُحْرِقَ مَتَاعُهُ فَوُجِدَ فِي مَتَاعِهِ مُصْحَفٌ فَقَالَ سَالِمٌ بِعْ هَذَا وَتَصَدَّقْ بِثَمَنِهِ
