Disbelief and Doubt

وَحِيلَ بَيْنَهُمْ وَبَيْنَ مَا يَشْتَهُونَ كَمَا فُعِلَ بِأَشْيَاعِهِم مِّن قَبْلُ ۚ إِنَّهُمْ كَانُوا۟ فِى شَكٍّ مُّرِيبٍۭ

And prevention will be placed between them and what they desire, as was done with their kind before. Indeed, they were in disquieting doubt [i.e., denial].

أَلَآ إِنَّهُمْ فِى مِرْيَةٍ مِّن لِّقَآءِ رَبِّهِمْ ۗ أَلَآ إِنَّهُۥ بِكُلِّ شَىْءٍ مُّحِيطٌۢ

Unquestionably, they are in doubt about the meeting with their Lord. Unquestionably He is, of all things, encompassing.

بَلْ هُمْ فِى شَكٍّ يَلْعَبُونَ

But they are in doubt, amusing themselves.
