Arabic (Original)
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.
English Translation
When Ali burned some people who had apostatized from Islam, the news reached Ibn 'Abbas, who said: "I would not have burned them with fire, for the Messenger of Allah (peace be upon him) said: 'Do not punish with the punishment of Allah.' But I would have executed them, because the Messenger of Allah (peace be upon him) said: 'Whoever changes his religion, execute him.'" When this reached Ali, he said: "How right Ibn 'Abbas is!"
