Is God's prescription of eternal hell for kâfirūn (infidels) in the Quran evil? Contesting Aijaz's understanding of kufr (infidelity) and an analysis of eternal punishment in the Quran

This article concerns the problem of eternal hell in Islam as an aporetic problem of evil with a focus on Aijaz's description of the Islamic soteriology. I contest his description of Islamic culpability and his claim that all non-Muslims are regarded as kâfir and consigned to eternal hell. First, I aim to illustrate the pitfalls in his line of argumentation such as crude generalizations and selective reading of the Islamic sources, which seem to render his argument a strawman fallacy. I offer a more accurate analysis of the Islamic view, by arguing that only a limited group of people who fight against truth through evil actions are considered as kâfir. Second, building on my analysis of the notion of kâfir, I address the question whether God's perfect love and wisdom are compatible with limited salvific exclusivism. Thus, I aim to elaborate on the rationale behind the prescription of eternal punishment for the kâfir in the Quran in the rest of the article, by arguing that the kâfir is incapable of genuine repentance due to his character formed by his free choices. This, in turn, makes it impossible to achieve retributive justice through a finite punishment concerning the kâfir's evil actions.
