(But this day We save thee in your body) We save your cadaver in its armour (that thou mayst be a portent) that you may be a lesson, such that they do not claim what you claimed and know that you are not a god (for those after thee) among the disbelievers. (Lo! most of mankind) i.e. the disbelievers (are heedless of) are deniers of (Our portents) Our Scripture and Messenger.
