إِنَّ ٱلَّذِينَ يَكۡفُرُونَ بِـَٔايَٰتِ ٱللَّهِ وَيَقۡتُلُونَ ٱلنَّبِيِّـۧنَ بِغَيۡرِ حَقّٖ وَيَقۡتُلُونَ ٱلَّذِينَ يَأۡمُرُونَ بِٱلۡقِسۡطِ مِنَ ٱلنَّاسِ فَبَشِّرۡهُم بِعَذَابٍ أَلِيمٍ٢١

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.
