Verses 3-6 of Chapter 45:

The fact is that there are countless Signs in the heavens and the earth for those who believe. And in your own creation and in the animals, whom Allah is scattering (all over the earth), there are signs for those who affirm faith. And in the difference of the night and day, and in the provisions that Allah sends down from the heaven, whereby He revives the earth after its death, and in the circulation of the winds, there are many signs for those who use their common sense. These are the Revelations of Allah, which We are rehearsing to you accurately. Then, what is there after Allah and His Revelations in which they will believe.
