According to search-discovered classical Islamic scholarship, the 'flash of fire followed by smoke' mentioned in Quran 55:35 refers to a specific and severe eschatological punishment. Exegetes like Ibn Abbas and Mujahid defined the key terms as 'Shuwaz' (شُوَاظٌ), a pure, smokeless flame, and 'Nuhas' (نُحَاسٌ), interpreted as either a suffocating smoke without flame or molten copper. The tafsir of Ibn Kathir and Al-Tabari clarifies that this punishment is directed at both jinn and mankind on the Day of Judgment. It serves as the consequence should they attempt to defy Allah's command and flee from the bounds of divine accountability, as challenged in the preceding verses. The verse concludes with the definitive statement that they will be utterly unable to defend themselves ('fa-lā tantaṣirān'), cementing it as a powerful Quranic warning of the absolute authority of Allah and the inescapability of His justice in the Hereafter.
