Killing Apostates and People who Strive to cause Mischief - Section 1
عَنْ عِكْرِمَةَ قَالَ: أُتِيَ عَلِيٌّ بِزَنَادِقَةٍ فَأَحْرَقَهُمْ فَبَلَغَ ذَلِكَ ابْنَ عَبَّاسٍ فَقَالَ: لَوْ كُنْتُ أَنَا لَمْ أُحْرِقْهُمْ لِنَهْيِ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَا تُعَذِّبُوا بِعَذَابِ اللَّهِ» وَلَقَتَلْتُهُمْ لِقَوْلِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ بَدَّلَ دِينَهُ فَاقْتُلُوهُ» . رَوَاهُ الْبُخَارِيُّ
‘Ikrima told that when some heretics were brought to ‘Ali he had them burned, and that when Ibn ‘Abbas heard of it he said that if it had been he, he would not have had them burned because of God’s Messenger's prohibition, “Do not inflict God’s punishment on anyone”, but would have had them killed on account of the statement made by God’s Messenger, “Kill those who change their religion.” Bukhari transmitted it.
