According to search-discovered classical Islamic scholarship, the number seventy (سبعين - Sab'een) in the Quran often transcends its literal value, serving as a powerful rhetorical device to signify a large, complete, or immense quantity. This usage is rooted in classical Arabic, where numbers like seven and seventy were commonly used to denote abundance and finality. Tafsir scholars such as Ibn Kathir and Al-Qurtubi explain that while 'seventy' can be literal, as in the seventy men chosen by Moses (7:155) or the seventy-cubit chain of punishment (69:32), its most profound use is symbolic. In Surah At-Tawbah (9:80), the statement that Allah will not forgive the hypocrites even if the Prophet asks seventy times is understood by consensus to mean He will *never* forgive them, with 'seventy' indicating an infinite number of pleas. This synthesis across the three Quranic contexts reveals 'seventy' as a divinely chosen number to emphasize the gravity and scale of selection, judgment, and consequence.
