(Ali-Imran) 3 : 21
إِنَّ الَّذِينَ يَكْفُرُونَ بِآيَاتِ اللَّهِ وَيَقْتُلُونَ النَّبِيِّينَ بِغَيْرِ حَقٍّ وَيَقْتُلُونَ الَّذِينَ يَأْمُرُونَ بِالْقِسْطِ مِنَ النَّاسِ فَبَشِّرْهُمْ بِعَذَابٍ أَلِيمٍ
Indeed, those who are hiding verses of Lord Allah, slaying the Prophets without any Truth, and killing those who are commanding with Justice among the mankind, then you announce them about the Herald of a painful punishment.
