Plain UnderstandingThe Arabic uses the word 'Umm' (Mother), describing the terrifying reality of falling into an abyss as a desperate return. Without God, the soul plummets endlessly into a void of its own making.
Historical Context (Al-Qurtubi)Al-Qurtubi and other classical exegetes note the striking use of the word "mother" (Umm) here. Just as a child falls into the embrace of its mother, the one who rejected Truth will fall headfirst into the abyss, for it is the only "home" their earthly deeds have prepared for them.
