النَّارُ يُعْرَضُونَ عَلَيْهَا غُدُوًّا وَعَشِيًّا
They are exposed to the Fire morning and evening. (Qurʾan 40:46)
The verse refers to Pharaoh's people being presented before the Fire prior to the final command at the Resurrection. The expression “morning and evening” conveys repeated exposure in the language of the verse.
The key inferential point is the sequence: the exposure is stated first; then, when the Hour arrives, a further order concerning severe punishment is given. The sequence is used to support punishment in the interval before the final resurrection.
