then Allah’s making expiation obligatory for accidental killing indicates and implies that expiation is likewise obligatory for deliberate killing.

Other scholars say that there is no expiation for deliberate killing. They cite as evidence that Allah made accidental killing a condition for the obligation of expiation, saying: “Whoever kills a believer by mistake...” Then He says: “Whoever kills a believer intentionally, his recompense is Hell...” [al-Nisa 4:93]. Thus, He did not prescribe anything for him that would protect him from the Fire.

They also say: deliberate killing is too grave a crime for expiation to apply to it; rather, it carries only this severe threat. This view is more correct.
