وَمَنْ هَابَ أَسْبَابَ الْمَنَايَا يَنَلْنَهُ ۞ وَإِنْ يَرْقَ أَسْبَابَ السَّمَاءِ بِسُلَّمِ
Whoever fears the causes of death will still be overtaken by it, even if he could ascend the paths of heaven by a ladder.
Hāba means “feared.” The feminine plural subject encoded in yanalnahu refers to al-manāyā (deaths). The imagined ladder rising to heaven exaggerates the height of a possible refuge only to deny its effectiveness. The point is the inevitability of mortality, not an instruction to disregard ordinary safety.
