According to search-discovered classical Islamic scholarship, the Quranic phrase 'a Paradise as vast as the heavens and the earth' (jannatin ʿarḍuhā as-samāwātu wal-ʾarḍ) is a profound metaphor signifying the incomprehensible scale of the divine reward prepared for the righteous (Al-Muttaqin). [1] In his tafsir, Ibn Kathir explains that this description in Surah Al-Imran (3:133) serves to draw the believer's attention to the immense spaciousness of Paradise. [7, 9] This view is supported by Al-Qurtubi, who clarifies that this is a linguistic expression used by Arabs to denote ultimate vastness, not a literal geometric measurement. [3, 14] The deliberate mention of 'width' (ʿarḍ), as noted by scholars like Al-Baghawi, is a powerful rhetorical device; if the shortest dimension is already on a cosmic scale, the true expanse is known only to Allah. [18] This imagery functions as a supreme spiritual motivation, encouraging believers to hasten towards forgiveness and piety, for which the prize is a blissful abode of unimaginable grandeur.
