The Messenger of Allah ﷺ sent an expedition to Khath'am. Some people sought protection by having recourse to prostration, and were hastily killed. When the Prophet ﷺ heard that, he ordered half the blood-wit to be paid for them, saying: I am not responsible for any Muslim who stays among polytheists. They asked: Why, Messenger of Allah? He said: Their fires should not be visible to one another. Abu Dawud said: Hushaim, Ma'mar, Khalid b. al-Wasiti and a group of narrators have also narrated it, but did not mention Jarir. (Using translation from Abū Dāʾūd 2645)   

بَعَثَ رَسُولُ اللهِ ﷺ سَرِيَّةً إِلَى خَثْعَمٍ فَاعْتَصَمَ نَاسٌ مِنْهُمْ بِالسُّجُودِ وَأَسْرَعَ فِيهِمُ الْقَتْلُ فَبَلَغَ ذَلِكَ النَّبِيَّ ﷺ فَأَمَرَ لَهُمْ بِنِصْفِ الْعَقْلِ وَقَالَ أَنَا بَرِيءٌ مِنْ كُلِّ مُسْلِمٍ مُقِيمٍ بَيْنَ أَظْهُرِ الْمُشْرِكِينَ قَالُوا يَا رَسُولَ اللهِ وَلِمَ؟ قَالَ لَا تَرَايَا نَارَاهُمَا  

[Machine] On the authority of the Prophet ﷺ , he said: "Do not reside with the polytheists nor have intimate relations with them. Whosoever resides among them or has intimate relations with them is not one of us."  

عَنِ النَّبِيِّ ﷺ قَالَ لَا تُسَاكِنُوا الْمُشْرِكِينَ وَلَا تُجَامِعُوهُمْ فَمَنْ سَاكَنَهُمْ أَوْ جَامَعَهُمْ فَلَيْسَ مِنَّا
