Historical Context (Al-Tabari)When the Prophet ﷺ climbed Mount Safa to openly call his tribe to faith and warn them of divine accountability, Abu Lahab arrogantly dusted off his hands and shouted, "May you perish for the rest of this day! Did you gather us just for this?" God immediately responded, turning Abu Lahab's own hateful curse back upon him, ensuring that it is the oppressor—not the Prophet—who will ultimately perish.
Purification of the Self (Al-Ghazali)The "hands" represent a human being's capacity for action, control, and influence. When a person uses their God-given faculties to wage a deliberate war against the Divine out of sheer ego, those very faculties become the instruments of their own spiritual death.
