وَمَن يَقۡتُلۡ مُؤۡمِنٗا مُّتَعَمِّدٗا فَجَزَآؤُهُۥ جَهَنَّمُ خَٰلِدٗا فِيهَا وَغَضِبَ ٱللَّهُ عَلَيۡهِ وَلَعَنَهُۥ وَأَعَدَّ لَهُۥ عَذَابًا عَظِيمٗا

Wa mai yaqtul mu'minam muta'ammidan fajazaaa'uhoo Jahannamu khaalidan feehaa wa ghadibal laahu' alaihi wa la'anahoo wa a'adda lahoo 'azaaban 'azeemaa

If a man kills a believer intentionally, his recompense is Hell, to abide therein (For ever): And the wrath and the curse of Allah are upon him, and a dreadful penalty is prepared for him.

— An-Nisa' (ٱلنِّسَاء), 4:93
