On the day when (some) faces shall turn white and (some) faces shall turn black; then as to those whose faces turn black: Did you disbelieve after your believing? Taste therefore the chastisement because you disbelieved.

Do not make excuses; you have denied indeed after you had believed; if We pardon a party of you, We will chastise (another) party because they are guilty.

They swear by Allah that they did not speak, and certainly they did speak, the word of unbelief, and disbelieved after their Islam, and they had determined upon what they have not been able to effect, and they did not find fault except because Allah and His Messenger enriched them out of His grace; therefore if they repent, it will be good for them; and if they turn back, Allah will chastise them with a painful chastisement in this world and the hereafter, and they shall not have in the land any guardian or a helper.

And He it is Who created the heavens and the earth in six periods-- and His dominion (extends) on the water-- that He might manifest to you, which of you is best in action, and if you say, surely you shall be raised up after death, those who disbelieve would certainly say: This is nothing but clear magic.

And they disbelieved in it before, and they utter conjectures with regard to the unseen from a distant place.

Say: Tell me if it is from Allah; then you disbelieve in it, who is in greater error than he who is in a prolonged opposition?
