Al-Qaria ('The Calamity'), 11 Meccan verses, names the striking Day when people are like scattered moths and mountains like carded wool. It sets the scales: the one whose good deeds weigh heavy has a pleasant life, while the one whose scales are light falls to 'a bottomless pit' (101:6-11). Al-Qaria's imagery of scattered moths and carded wool (101:4-5), read by classical commentators as deliberately homely, everyday similes chosen for their immediate accessibility to a seventh century Arabian audience rather than as abstract cosmological description, is regularly compared by scholars of Quranic rhetoric with the similarly humble similes deployed in neighbouring short surahs, spiders' webs, panting horses, striking birds.
The surah's naming of the fire simply as 'a scorching Fire' in its closing verse, without further elaboration, is characteristic of the terse, unembellished style scholars associate with the earliest layer of Meccan revelation. Al-Qaria shares its central image, the scales of deeds, with the more extended treatment of the same idea in Al-Araf and Al-Muminun, and classical commentators read the shorter surah as a compressed, standalone restatement of a judgement scene developed at greater narrative length elsewhere in the Quran. Its closing description of the failed scales leading to 'a pit' identified in some transmissions with Hawiya, understood as one of several names the Quran and hadith literature use for different aspects or levels of hellfire, a nomenclature later systematised, with varying detail, in classical Islamic eschatological writing well beyond what the Quran itself specifies.
