Qur'an 3:21 · Aal-i-Imraan

إِنَّ ٱلَّذِينَ يَكْفُرُونَ بِـَٔايَٰتِ ٱللَّهِ وَيَقْتُلُونَ ٱلنَّبِيِّۦنَ بِغَيْرِ حَقٍّۢ وَيَقْتُلُونَ ٱلَّذِينَ يَأْمُرُونَ بِٱلْقِسْطِ مِنَ ٱلنَّاسِ فَبَشِّرْهُم بِعَذَابٍ أَلِيمٍ

(21) Those who disbelieve in the signs of Allāh and kill the prophets without right and kill those who order justice from among the people - give them tidings of a painful punishment.
