Imam al-Saadi says in his commentary on the verse, “But whoever kills a believer intentionally – his recompense is Hell, wherein he will abide eternally, and Allah has become angry with him and has cursed him and has prepared for him a great punishment.” [An-Nisa: 93], “Here the punishment of the murderer is mentioned deliberately. It is the day his heart trembles, and his heart is broken, and he loses his mind. There is no enormity greater than this nor similar to it. His punishment is hell. That great sin is rewarded with hell with its great torment, humiliation and disgrace, and incurs the wrath of the Almighty. He has forgone salvation and earns only disappointment and loss.”
