وَلَن يُؤَخِّرَ ٱللَّهُ نَفْسًا إِذَا جَآءَ أَجَلُهَا ۚ وَٱللَّهُ خَبِيرٌۢ بِمَا تَعْمَلُونَ
Wa lany yu 'akhkhiral laahu nafsan izaa jaaa'a ajaluhaa; wallaahu khabeerum bimaa ta'maloon

The verb here is the one the dying man used a line earlier when he asked to be held back a little longer, so the request is refused in its own vocabulary.

It closes a chapter about people whose conduct never caught up with their words.
