Quran 27:4 — The Ant (Al-Naml)

Those who do not believe in the Hereafter, we adorn their works in their eyes. Thus, they continue to blunder.

[27:3] Who observe the Contact Prayers (Salat), give the obligatory charity (Zakat), and they are, with regard to the Hereafter, absolutely certain.

[27:5] It is these who incur the worst retribution, and in the Hereafter, they will be the worst losers.
