And when they meet those who believe they say: We believe, and when they are alone one with another they say: Do you talk to them of what Allah has disclosed to you that they may contend with you by this before your Lord? Do you not then understand?

And those who disbelieve say: By no means will we believe in this Quran, nor in that which is before it; and could you see when the unjust shall be made to stand before their Lord, bandying words one with another! Those who were reckoned weak shall say to those who were proud: Had it not been for you we would certainly have been believers.
