عَنْ حَمْزَةَ بْنِ عَمْرٍو الْأَسْلَمِيِّ صَاحِبِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ رَضِيَ اللَّهُ عَنْهُ حَدَّثَهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ بَعَثَهُ وَرَهْطًا مَعَهُ إِلَى رَجُلٍ مِنْ عُذْرَةَ فَقَالَ إِنْ قَدَرْتُمْ عَلَى فُلَانٍ فَأَحْرِقُوهُ بِالنَّارِ فَانْطَلَقُوا حَتَّى إِذَا تَوَارَوْا مِنْهُ نَادَاهُمْ أَوْ أَرْسَلَ فِي أَثَرِهِمْ فَرَدُّوهُمْ ثُمَّ قَالَ إِنْ أَنْتُمْ قَدَرْتُمْ عَلَيْهِ فَاقْتُلُوهُ وَلَا تُحْرِقُوهُ بِالنَّارِ فَإِنَّمَا يُعَذِّبُ بِالنَّارِ رَبُّ النَّارِ
It is narrated from the Companion of the Messenger, Sayyiduna Hamza bin Amr Aslami (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) sent him along with an army to a man from the tribe of ‘Uzrah and said: If you overpower so-and-so, then burn him with fire. So he set out, and when he was about to be out of sight of the Prophet (peace and blessings be upon him), the Prophet (peace and blessings be upon him) called him back by sending someone after him, and then said: If you overpower that man, then kill him, do not burn him with fire, for only the Lord of the Fire punishes with fire.
