وَٱلَّذِينَ كَفَرُوٓاْ أَعۡمَٰلُهُمۡ كَسَرَابِۭ بِقِيعَةٖ يَحۡسَبُهُ ٱلظَّمۡـَٔانُ مَآءً حَتَّىٰٓ إِذَا جَآءَهُۥ لَمۡ يَجِدۡهُ شَيۡـٔٗا وَوَجَدَ ٱللَّهَ عِندَهُۥ فَوَفَّىٰهُ حِسَابَهُۥۗ وَٱللَّهُ سَرِيعُ ٱلۡحِسَابِ

But the Unbelievers,- their deeds are like a mirage in sandy deserts, which the man parched with thirst mistakes for water; until when he comes up to it, he finds it to be nothing: But he finds Allah (ever) with him, and Allah will pay him his account: and Allah is swift in taking account.

— An-Nur (ٱلنُّور), 24:39
