Ali 'Imran 3:21

Inna allatheena yakfuroona bi-ayatiAllahi wayaqtuloona annabiyyeena bighayri haqqinwayaqtuloona allatheena ya/muroona bilqistimina annasi fabashshirhum biAAathabin aleem

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.

Surely, those who reject the verses of Allah and slay the prophets unjustly, and slay those of the people who bid justice, give them ‘the good news’ of a painful punishment.
