45:17And We gave them precise rulings. They fell into dispute only after knowledge came to them, out of mutual rivalry. Your Lord will judge between them on the Day of Resurrection regarding the things they differed about.

45:21Do those who perpetrate the evil deeds assume that We will regard them as equal to those who believe and do righteous deeds, whether in their life or their death? Evil is their judgment!

45:24And they say, “There is nothing but this our present life; we die and we live, and nothing destroys us except time.” But they have no knowledge of that; they are only guessing.

45:25When Our clarifying Verses are recited to them, their only argument is to say, “Bring back our ancestors, if you are truthful.”

45:26Say, “God gives you life, then He makes you die; then He gathers you for the Day of Resurrection, about which there is no doubt. But most people do not know.”

45:27To God belongs the kingship of the heavens and the earth. On the Day when the Hour takes place, on that Day the falsifiers will lose.

45:35That is because you took God’s revelations for a joke, and the worldly life lured you.” So today they will not be brought out of it, and they will not be allowed to repent.
