وَمَن يَقۡتُلۡ مُؤۡمِنࣰ ا مُّتَعَمِّدࣰ ا فَجَزَآؤُهُۥ جَهَنَّمُ خَٰلِدࣰ ا فِيهَا وَغَضِبَ ٱللَّهُ عَلَيۡهِ وَلَعَنَهُۥ وَأَعَدَّ لَهُۥ عَذَابًا عَظِيمࣰ ا۝٩٣

93. But whoever kills a believer intentionally - his recompense is Hell, wherein he will abide eternally, and Allah has become angry with him and has cursed him and has prepared for him a great punishment
