According to search-discovered classical Islamic scholarship, the concept of the sky being 'rent asunder' is a literal and monumental sign marking the commencement of the Day of Judgment (Yawm al-Qiyamah). Across six key verses, the Quran uses powerful Arabic terms like 'infatarat' (cleaved apart, 82:1) and 'inshaqqat' (split open, 84:1) to describe this event. The great exegete Ibn Kathir explains this as the complete dissolution of the heavens and the cosmic order, which will turn reddish like molten brass, as mentioned in Surah Ar-Rahman (55:37). Al-Tabari, focusing on the linguistic depth, highlights that these words denote a powerful, irreversible tearing that reveals the fragility of creation. This thematic synthesis across all references illustrates that the splitting of the sky is a terrifying manifestation of Allah's absolute power, signaling the end of the worldly realm and the beginning of the final accountability.
