Surah 29. Al-Ankabut, Ayah 20

Cf., for example, {23:12-14}, which alludes to man's coming into existence out of most primitive elements, and gradually evolving into a highly complex being endowed not only with a physical body but also with a mind, with feelings, and instincts.

Travel through the earth: again, literally as well as symbolically. If we actually go through this wide earth, we shall see the wonderful things in His Creation-the Grand Canyon and the Niagaras in America, beautiful harbors like that at Sydney in Australia, mountains like Fujiyama, the Himalayas, and Elburz in Asia, the Nile with its wonderful cataracts in Africa, the Fiords of Norway, the Geysers of Iceland, the city of the midnight sun in Tromsoe, and innumerable wonders everywhere. But wonders upon wonders are disclosed in the constitution of matter itself, the atom, and the forces of energy, as also in the instincts of animals, and the minds and capacities of man. And there is no limit to these things. Worlds upon worlds are created and transformed every moment, within and presumably beyond man's vision. From what we know we can judge of the unknown.
