Narrated Umar:
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.'
