Surah An-Nisaوَمَن يَقۡتُلۡ مُؤۡمِنٗا مُّتَعَمِّدٗا فَجَزَآؤُهُۥ جَهَنَّمُ خَٰلِدٗا فِيهَا وَغَضِبَ ٱللَّهُ عَلَيۡهِ وَلَعَنَهُۥ وَأَعَدَّ لَهُۥ عَذَابًا عَظِيمٗا
As for anyone who kills a mumin deliberately, his repayment is Hell, remaining in it for ever. Allah is angry with him and has cursed him, and has prepared for him a terrible punishment
