Surah 4:93
"Whoever kills a believer intentionally, his payment is Gehenna – there to remain. God will be angry with him, and curse him, and prepare a great punishment for him."
Punishment for Intentional Murder
Opposing Verses
Surah 2:178 → "You who believe! The (law of) retaliation is prescribed for you in (the case of) those who have been killed: the free man for the free man, the slave for the slave, and the female for the female. But whoever is granted any pardon for it by his brother, it should be (done) rightfully, and payment should be rendered with kindness. That is a concession from your Lord, and a mercy. Whoever transgresses after that – for him (there is) a painful punishment."
What is the consequence for intentionally killing a believer? One verse states the penalty is eternal Hell and God's curse, while another verse allows for a worldly resolution through pardon and payment of blood money as a mercy from God.
