[Machine] Abu Bakr used to instruct his governors, when he would send them out during apostasy, that if you come across a house and hear the call to prayer, then hold off until you ask them why they rebelled. But if you do not hear the call to prayer, then attack, kill, burn, and expend all efforts in killing and wounding, with no concern for weakness in causing death to your Prophet ﷺ.
كَانَ أَبُو بَكْرٍ ؓ يَأْمُرُ أُمَرَاءَهُ حِينَ كَانَ يَبْعَثُهُمْ فِي الرِّدَّةِ إِذَا غَشِيتُمْ دَارًا فَإِنْ سَمِعْتُمْ بِهَا أَذَانًا بِالصَّلَاةِ فَكُفُّوا حَتَّى تَسْأَلُوهُمْ مَاذَا نَقَمُوا فَإِنْ لَمْ تَسْمَعُوا أَذَانًا فَشُنُّوهَا غَارَةً وَاقْتُلُوا وَحَرِّقُوا وَانْهَكُوا فِي الْقَتْلِ وَالْجِرَاحِ لَا يُرَى بِكُمْ وَهَنٌ لِمَوْتِ نَبِيِّكُمْ ﷺ
