According to search-discovered classical Islamic scholarship, the 'warning to resurrection deniers' is a pivotal Quranic theme addressing the materialist objection to the afterlife. As detailed in the tafsir of Ibn Kathir on Surah Al-Isra, verses 49-52, the Quran directly confronts the skeptical question: 'When we are bones and crumbled dust, will we really be raised as a new creation?' The divine response, as analyzed by scholars like Al-Qurtubi, is a powerful logical argument challenging deniers to consider something even harder to resurrect, like 'stones or iron,' yet affirming that 'He Who created you first' has the absolute power to do so. This argument from the first creation is a cornerstone of Islamic theology, asserting that recreating is a lesser feat than creating from nothing. The synthesis of these verses establishes a definitive proof of God's omnipotence and the certainty of the Day of Judgment, serving as a solemn warning that the event is 'perhaps it is near!'.
