People deny the revelations of God without comprehending them by knowledge!

Verses 83-84 of Chapter 27:

And (remind them of) the Day when We shall gather out of every nation a host of those who denied Our revelations, and they will be set in array; Till, when they come (before their Lord), He will say: Did ye deny My revelations when ye could not compass them in knowledge, or what was it that ye did?
