Ar-Ra'd · 13:3

3. 3He, may He be glorified, is the One Who spread out the earth and created on it firm mountains so that it does not cause the people to become unsettled. From all types of fruit He made two kinds, like the male and female in animals. He draws the veil of night over the day so that it becomes dark after being bright. In that which is mentioned, there are signs and proof for a people who reflect and ponder over Allah’s creation, for they are the ones who benefit from such signs and proof.
