Surah Ali 'Imran — Ayah 21 (3:21)
إِنَّ ٱلَّذِينَ يَكۡفُرُونَ بِـَٔايَٰتِ ٱللَّهِ وَيَقۡتُلُونَ ٱلنَّبِيِّـۧنَ بِغَيۡرِ حَقّٖ وَيَقۡتُلُونَ ٱلَّذِينَ يَأۡمُرُونَ بِٱلۡقِسۡطِ مِنَ ٱلنَّاسِ فَبَشِّرۡهُم بِعَذَابٍ أَلِيمٍ ٢١
English translation (Saheeh International)
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.
Brief commentary
Those who disbelieve in Allah’s signs, which show that He alone is the Lord and the One worthy of being worshipped, kill His prophets wrongly due to hatred, and kill those who call for justice by commanding good and forbidding evil – give these murderous disbelievers news of a painful punishment.
