Although the first and basic aim of the Qur'an, according to what it says itself, is only to guide man to the great road of contentment and prosperity in the life of this world, the world of man, but on the way, in pursuing this aim, it expresses many truths from human knowledge in the natural sciences, in physiology and astronomy. And this is itself another great sign of the wonder of the Qur'an. For the Prophet, according to the definite testimony of history, had never studied, grew up in an environment completely devoid of human knowledge and science (except literature), and was far from the centers of science of those days - Greece, Rome and Iran. Now let us see some indications of this wonder.
1. Meteorology is a very new science. The knowledge of former people about the phenomena of clouds, wind, rain and snow did not go beyond conjecture and what they could see, and, generally speaking, it had an air of imaginativeness and chance and was never established on a scientific basis. Captains and farmers both had their signs and indications for forecasting wind and rain, but they did not really understand these phenomena.
Thus things went on for thousands of years, till, in the 17th century A.D., the thermometer, and in the 19th century the telegraph, and, gradually, other things necessary for meteorology were invented and discovered. In their turn, scientists settled down to research, till, in the first half of the 20th century, the Norwegian scientist, Byerkness, succeeded in discovering the general laws of the formation and movements of clouds and the occurrence of storms and rains in all places. After him, the extent of discoveries in this science, as in other areas, progressed: the rain-bearing properties of clouds, how rain is released from them, the formation and occurrence of hail, matters relating to thunderbolts and thunder and lightening and storms in tropical areas, air currents near the surface of the earth, and other matters, till knowledge reached extensive limits. But fifteen centuries ago, when the Qur'an told about the winds and the rain and other phenomena, it was right when it told us about the latest, newest discoveries of meteorology.
For example, it has now been proved that it is possible for a cloud to reach saturation point but to yield no rain, and for it to be just microscopic particles tiny enough to hang suspended in the air and not to fall and cause rain; however, by means of invisible particles of salt which are blown by the wind from the surface of the sea it will rain. Or, something more important; the humidity in the air gathers round the crystallised snow flakes which lie at high altitudes and which are scattered by the wind. Eventually small drops and the first rain unite together, and, as a result of mixing and colliding together in the wind, they gradually become bigger and bigger, and because of their own relatively heavy weight fall from the massed clouds. This is what the Qur'an made clear 15 centuries ago:
"And We send winds for making fruitful, and then We send down water from the sky, thus We give it unto you to drink of it". (XV: 22)
2. Until the invention of the aircraft and the possibility of high-altitude flying, man's knowledge and experience did not encompass needles of ice beyond the clouds. Till then no one knew that mountains of ice-needles existed in the sky above man's heads. But the Qur'an is very clear when it says:
"He sendeth down from the sky, from mountains therein, hail...". (XXIV: 43)
3. Living things in other worlds. Man, with the help of his knowledge of space, has set foot on the moon, but the matter of the existence of living things on other worlds has not proceeded beyond theory, and we can say that, from many signs, only it is possible that there are living things such as animals or man on some other planets and stars. But the Qur'an declares unambiguously:
And of His signs is the creation of the heavens and the earth and of what He hath spread out in both of them of animate beings, and for their gathering together when He willeth, He is All-PowerfuL" (XLII: 29)
4. In Surah 36, verse 36, we have:
"Glory be to He Who created all the pairs of what the earth produces, and of themselves, and of what they know not."
And in Surah 20, verse 53, we read:
"And He sent down water out of the sky, and therewith We have brought forth various pairs of plants."
In times when man's knowledge did not permit the respected interpreters of the Qur'an to know that plants and growing things came in pairs and couples, they interpreted and observed pairing in classes, species or by form and matter or other philosophical terms which do not exist in the pages of the Qur'an. But today, on the basis of new research, it has been discovered that not only are men and animals created in pairs, but other living things also. One of the most amazing phenomena in the world is the pairing and fertilizations of plants, which is all explained in natural science books.
