"And those who disbelieve say: We believe not in this Qur'an, nor in that which is before it. And if thou couldst see when the wrongdoers are made to stand before their Lord, throwing back the blame one to another! Those who were reckoned weak say to those who were proud: Had it not been for you, we would have been believers. Those who were proud say to those who were deemed weak: Did we turn you away from the guidance after it had come to you? Nay, you (yourselves) were guilty. And those who were deemed weak say to those who were proud: Nay, (it was your) planning by night and day when you told us to disbelieve in Allah and to set up likes with Him. And they will manifest regret when they see the chastisement. And We put shackles on the necks of those who disbelieve. They will not be requited but for what they did."
