يَٰٓأَيُّهَا ٱلنَّاسُ إِنَّ وَعْدَ ٱللَّهِ حَقٌّ ۖ فَلَا تَغُرَّنَّكُمُ ٱلْحَيَوٰةُ ٱلدُّنْيَا ۖ وَلَا يَغُرَّنَّكُم بِٱللَّهِ ٱلْغَرُورُ
Commentary:
It is really love of the world that leads man to sin. This is why "the present life" has been mentioned in the verse before the mention of "the Deceiver" who is Satan. This shows that it is man himself who first becomes mentally corrupt and then Satan comes to deceive and lead him astray.
