Disbelief and Mockery of Divine Truth

وَيَقُولُونَ مَتَىٰ هَـٰذَا ٱلْوَعْدُ إِن كُنتُمْ صَـٰدِقِينَ

And they say, "When is [the fulfillment of] this promise, if you should be truthful?"

أَيَعِدُكُمْ أَنَّكُمْ إِذَا مِتُّمْ وَكُنتُمْ تُرَابًا وَعِظَـٰمًا أَنَّكُم مُّخْرَجُونَ

Does he promise you that when you have died and become dust and bones that you will be brought forth [once more]?
