حَدَّثَنَا إِسْمَاعِيلُ حَدَّثَنَا أَيُّوبُ عَنْ عِكْرِمَةَ أَنَّ عَلِيًّا حَرَّقَ نَاسًا ارْتَدُّوا عَنْ الْإِسْلَامِ فَبَلَغَ ذَلِكَ ابْنَ عَبَّاسٍ فَقَالَ لَمْ أَكُنْ لِأُحَرِّقَهُمْ بِالنَّارِ وَإِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لَا تُعَذِّبُوا بِعَذَابِ اللَّهِ وَكُنْتُ قَاتِلَهُمْ لِقَوْلِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَنْ بَدَّلَ دِينَهُ فَاقْتُلُوهُ فَبَلَغَ ذَلِكَ عَلِيًّا كَرَّمَ اللَّهُ وَجْهَهُ فَقَالَ وَيْحَ ابْنِ أُمِّ ابْنِ عَبَّاسٍ
مسند امام احمد بن حنبل · Hadith 1871
It was narrated from 'Ikrimah that 'Ali burned some people who apostatized from Islam. News of that reached Ibn 'Abbas and he said: I would not have burned them with fire. The Messenger of Allah (PBUH) said: "Do not punish people with the punishment of Allah." I would have executed them, because the Messenger of Allah (PBUH) said: "Whoever changes his religion, execute him." News of that reached 'Ali (RA) and he said: Woe to the son of the mother of Ibn 'Abbas.
