An-Nisa 4:93 ومن يقتل مومنا متعمدا فجزاوه جهنم خالدا فيها وغضب الله عليه ولعنه واعد له عذابا عظيما ٩٣
وَمَن
يَقۡتُلۡ
مُؤۡمِنٗا
مُّتَعَمِّدٗا
فَجَزَآؤُهُۥ
جَهَنَّمُ
خَٰلِدٗا
فِيهَا
وَغَضِبَ
ٱللَّهُ
عَلَيۡهِ
وَلَعَنَهُۥ
وَأَعَدَّ
لَهُۥ
عَذَابًا
عَظِيمٗا
٩٣
Whoso slayeth a believer of set purpose, his reward is hell for ever. Allah is wroth against him and He hath cursed him and prepared for him an awful doom.
