Surah Aali Imran (The Family of Imran), Verse 21

اِنَّ الَّذِیْنَ یَكْفُرُوْنَ بِاٰیٰتِ اللّٰهِ وَیَقْتُلُوْنَ النَّبِیّٖنَ بِغَیْرِ حَقٍّ وَّیَقْتُلُوْنَ الَّذِیْنَ یَاْمُرُوْنَ بِالْقِسْطِ مِنَ النَّاسِ فَبَشِّرْهُمْ بِعَذَابٍ اَلِیْمٍ ۟

Innal lazeena yakfuroona bi Aayaatil laahi wa yaqtuloonan Nabiyyeena bighairi haqqinw wa yaqtuloonal lazeena ya'muroona bilqisti minannaasi fabashirhum bi'azaabin aleem

“As to those who deny the Signs of Allah and in defiance of right, slay the prophets, and slay those who teach just dealing with mankind, announce to them a grievous penalty.”
