إِنَّ ٱلَّذِينَ يَكۡفُرُونَ بِـَٔايَٰتِ ٱللَّهِ وَيَقۡتُلُونَ ٱلنَّبِيِّـۧنَ بِغَيۡرِ حَقّٖ وَيَقۡتُلُونَ ٱلَّذِينَ يَأۡمُرُونَ بِٱلۡقِسۡطِ مِنَ ٱلنَّاسِ فَبَشِّرۡهُم بِعَذَابٍ أَلِيمٍ
English translation: Indeed those who disbelieve in (the) Signs (of) Allah and they kill the Prophets without right and they kill those who order [with] justice among the people then give them tidings of a punishment painful
