أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ حَدَّثَنَا عَبْدُ الصَّمَدِ، قَالَ حَدَّثَنَا هِشَامٌ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، أَنَّ عَلِيًّا، أُتِيَ بِنَاسٍ مِنَ الزُّطِّ يَعْبُدُونَ وَثَنًا فَأَحْرَقَهُمْ، قَالَ ابْنُ عَبَّاسٍ إِنَّمَا قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم مَنْ بَدَّلَ دِينَهُ فَاقْتُلُوهُ .
It was narrated from Anas that : 'Ali came to some people of Az-Zutt, who worshipped idols, and burned them. Ibn 'Abbas said: "But the Messenger of Allah [ﷺ] said: 'Whoever changes his religion, kill him.'"
