"And the day when We gather from every nation a party from among those who rejected Our messages, then they will be formed into groups. Until, when they come, He will say did you reject My messages, while you did not comprehend them in knowledge? Or what was it that you did? And the word will come to pass against them because they were unjust, so they will not speak. See they not that We have made the night that they may rest therein, and the day to give light? Surely there are signs in this for a people who believe. And the day when the trumpet is blown, then those in the heavens and those in the earth will be struck with terror, except such as Allah please. And all shall come to Him abased. And thou seest the mountains -- thou thinkest them firmly fixed -- passing away as the passing away of the cloud; the handiwork of Allah, Who has made everything thoroughly. Surely He is Aware of what you do. Whoever brings good, he will have better than it; and they will be secure from terror that day. And whoever brings evil, these will be thrown down on their faces into the Fire. Are you rewarded aught except for what you did?"
