From Jarir bin 'Abdullah that the Messenger of Allah ﷺ sent a military expedition to Khath'am. So some people (living there) sought safety by prostrating, but they were met quickly and killed. News of this reached the Prophet ﷺ upon which he commanded that they be given half of the 'Aql (blood money). And he said: "I am free from every Muslim that lives among the idolaters." They said:"O Messenger of Allah: How is that ?" He said: "They should not see each other's campfires."
أَنَّ رَسُولَ اللَّهِ ﷺ بَعَثَ سَرِيَّةً إِلَى خَثْعَمٍ فَاعْتَصَمَ نَاسٌ بِالسُّجُودِ فَأَسْرَعَ فِيهِمُ الْقَتْلُ فَبَلَغَ ذَلِكَ النَّبِيَّ ﷺ فَأَمَرَ لَهُمْ بِنِصْفِ الْعَقْلِ وَقَالَ أَنَا بَرِيءٌ مِنْ كُلِّ مُسْلِمٍ يُقِيمُ بَيْنَ أَظْهُرِ الْمُشْرِكِينَ قَالُوا يَا رَسُولَ اللَّهِ وَلِمَ قَالَ لاَ تَرَايَا نَارَاهُمَا
