disbelief and skepticism

وَيَقُولُ ٱلْإِنسَـٰنُ أَءِذَا مَا مِتُّ لَسَوْفَ أُخْرَجُ حَيًّا

And man [i.e., the disbeliever] says, "When I have died, am I going to be brought forth alive?"

أَءِذَا مِتْنَا وَكُنَّا تُرَابًا ۖ ذَٰلِكَ رَجْعٌۢ بَعِيدٌ

When we have died and have become dust, [we will return to life]? That is a distant [i.e., unlikely] return."
