According to search-discovered classical Islamic scholarship, the Quranic event of mountains being 'scattered like dust' (wa idha al-jibalu nusifat, 77:10) is a literal and major sign of the Day of Judgment. Tafsir by authorities such as Ibn Kathir and Al-Tabari confirms that this describes the complete annihilation of the mountains, which are symbols of stability and permanence in this world. Across multiple verses, this event is powerfully depicted through various metaphors, such as mountains becoming like 'carded wool' (101:5) or 'dunes of shifting sand' (73:14), to emphasize the utter dissolution of the physical realm by Allah's command. This thematic synthesis reveals that the destruction of the mountains serves as an undeniable demonstration of God's absolute power and the ephemeral nature of worldly existence, acting as a profound reminder of the imminent reality of the Hereafter.
