ثُمَّ أَنتُمۡ هَٰٓؤُلَآءِ تَقۡتُلُونَ أَنفُسَكُمۡ وَتُخۡرِجُونَ فَرِيقٗا مِّنكُم مِّن دِيَٰرِهِمۡ تَظَٰهَرُونَ عَلَيۡهِم بِٱلۡإِثۡمِ وَٱلۡعُدۡوَٰنِ وَإِن يَأۡتُوكُمۡ أُسَٰرَىٰ تُفَٰدُوهُمۡ وَهُوَ مُحَرَّمٌ عَلَيۡكُمۡ إِخۡرَاجُهُمۡۚ أَفَتُؤۡمِنُونَ بِبَعۡضِ ٱلۡكِتَٰبِ وَتَكۡفُرُونَ بِبَعۡضٖۚ فَمَا جَزَآءُ مَن يَفۡعَلُ ذَٰلِكَ مِنكُمۡ إِلَّا خِزۡيٞ فِي ٱلۡحَيَوٰةِ ٱلدُّنۡيَاۖ وَيَوۡمَ ٱلۡقِيَٰمَةِ يُرَدُّونَ إِلَىٰٓ أَشَدِّ ٱلۡعَذَابِۗ وَمَا ٱللَّهُ بِغَٰفِلٍ عَمَّا تَعۡمَلُونَ
Then here you are, killing one another and expelling a group of your people from their homes, aiding one another against them in sin and aggression. And if they come to you as captives, you ransom them, although their expulsion was forbidden to you. Do you then believe in part of the Scripture and deny another part? Then what is the recompense for those who do so among you except disgrace in this life, and on the Day of Resurrection they will be subjected to the severest torment? For Allah is not unaware of what you do.
