In the first part of this article on the scientific facts in the Quran, some astronomical facts mentioned were discussed. Here, we review some interesting facts about nature, including some points about mountains, the origin of life, the position of the sky and the seas merging together. 

5. Mountains with Deep Roots under the Ground

The Quran has used the word stakes to describe mountains: “It is He who has spread out the earth and set in it firm mountains” (13:3), “Did We not make the earth a resting place? and the mountains stakes?” (78:6-7). It means that mountains have deep roots under the ground surface. Mountains do have deep roots, and the word stakes is an accurate description for them. This fact was discovered only in the latter half of the 19th century. The presence of the mountains on the ground also helps to stabilize the crust of the earth [4]. They also hinder the earth-shaking. “He cast in the earth firm mountains lest it should shake with you” (16:15). This is known today under the theory of plate tectonics since the late 1960s [1].

6. The Origin of Life according to the Quran 

Life of a human being starts in water. From conception to birth, a fetus is protected and cushioned in a sack of water. A human body needs water in all its cells, organs, and tissues to help regulate its temperature and maintain other bodily functions. Plants also need enough hydration to perform photosynthesis, while animals consume water to carry out cell activity. Overall, water is an essential element for all living beings on earth. This fact was discovered only after the invention of the microscope. Now we know that all living things are made up of cells which are mostly made up of water. This fact has already been stated in the Quran: “We made every living thing out of water? Will they not then have faith?” (21:30).

7. The Sky as the Protector of the Earth

The sky plays several essential roles as the protector of the earth, such as filtering out the lethal rays of the sun. If there were no sky, the sun’s radiations would have killed off all life on earth. The sky also acts as a blanket around the earth, which protects the living things from freezing out by the cold just above the sky that is approximately -270°C. The greenhouse effect is another role that the sky plays. By warming the surface of the earth by means of heat retention, the sky reduces temperature extremes between day and night [2]. These protective roles of the sky were discovered by scientists in the 20th century. The Quran has mentioned this role of the sky as: “We made the sky a preserved roof and yet they are disregardful of its signs.” (21:32).

8. Where the Seas Meet

It has been discovered by the scientists that there is a barrier between the two different seas that meet. Hence, each of the seas has its own temperature, salinity, and density, like the Mediterranean Sea and Atlantic Ocean water. Despite large waves, strong currents, and tides in these seas, they neither mix nor do they transgress this barrier [3]. This phenomenon has been mentioned in the Quran as: “He merged the two seas, meeting each other. There is a barrier between them which they do not overstep.” (55:19-20). There is also a case where fresh (sweet) and saltwater meet. Here, the Quran talks about the existence of a forbidding partition along with the barrier: “It is He who merged the two seas: this one sweet and agreeable, and that one briny and bitter, and between the two He set a barrier and a forbidding hindrance.” (25:53). Modern science has discovered that in estuaries, where fresh and saltwater meet, there is a marked density discontinuity that separates the two layers. The salinity of this zone of separation (partition) is different from that of freshwater and that of saltwater. There is, therefore, the division of water in estuaries into three parts: freshwater, saltwater, and the partition [3].

In the two previous parts of this topic, we reviewed some astronomical facts and some points about our nature. Through the following lines, you can find out other scientific facts mentioned in the Quran.

Clouds and rain

Scientists have recently come to know that not every cloud is a rain cloud, but certain types of wind and clouds and definite steps are effective for forming rain clouds. They have found that one type of clouds go through the following steps to produce rain [1]. 
The clouds are pushed by the wind. Then, the small clouds join together to form a larger cloud, hence updrafts increase within the large cloud. Some phenomenon cause the cloud to stack up which stretches the cloud body into cooler regions where drops of water and hail form and begin to grow larger [1]. 
When these drops and hail become too heavy, they fall from the cloud as rain, hail, etc. [2]. This phenomenon is described in Surat Al-Nur: “Have you not regarded that Allah drives the clouds, then He composes them, then He piles them up, whereat you see the rain issuing from its midst?” (24:43). 

Deep seas and internal waves

In Surat Al-Nur, it is stated that: “Or like the manifold darkness in a deep sea, covered by billow upon billow, overcast by clouds, manifold [layers of] darkness, one on top of another: when he brings out his hand, he can hardly see it” (24:40). 
The darkness in deep seas mentioned in this verse is found around a depth of 200m and below where there is almost no light. Below a depth of 1000m, there is no light at all [3]. 
The verse states that there are two sets of waves, one above the other. Scientists called the lower waves as internal waves which “occur on density interfaces between layers of different densities” [4]. Since the deep waters of seas and oceans are denser than the waves above them, the internal waves cover them. They act like surface waves and might break just as them. They are not observable by the human eye, but can be detected by studying temperature or salinity changes at a given location [4].

The stages of human embryonic development in The Quran

Human embryonic development are described in the Quran as: “Certainly We created man from an extract of clay. Then We made him a drop of [seminal] fluid [lodged] in a secure abode. Then We created the drop of fluid as a clinging mass (alaqah). Then We created the clinging mass (alaqah) as a fleshy tissue (mudhqah).” (23:12-14). 
The word alaqah has three meanings in Arabic: leech, suspending thing, and blood clot. In comparison to leech, an embryo in the alaqah stage obtains nourishment from mother’s blood, same as the leech which feeds on the blood of others [2]. During the alaqah stage, the embryo is suspended in mother’s womb, hence, the word “suspended thing” fits, too. Finally, during the alaqah stage, due to the presence of relatively large volume of blood present in the embryo, it looks like a blood clot. Besides, the blood does not circulate until the end of the 3rd week, just as a blood clot. Hence, these three meanings describe accurately the embryo at this stage. 
The nest stage is described by the word mudhghah which means “chewed substance”. In fact, the somites at the back of the embryo “somewhat resemble teeth marks in a chewed substance” [5].

The creation in pairs

It has been recently discovered that everything in the universe is created in pair, as do male and female among living things. The parity among living creatures are stated in several the verses of the Quran as: “Immaculate is He who has created all the pairs of what the earth grows, and of themselves, and of what they do not know.” (36:36), “and that it is He who created the mates, the male and the female.” (53:45). And who created all the pairs and made for you the ships and the cattle such as you ride.” (43:12), “In all things We have created pairs so that you may take admonition.” (51:49). These verses mention the parity in things that grow from soil (i.e. plants), in animals, in those have been created from their own selves (i.e. humans), and things we do not know. 

The latter includes every other thing other than living things. The discovery of Paul Dirac known as “Parity”, for which he was awarded the Noble Prize in 1933, confirms this claim by stating that every matter has a pair called anti-matter [6]. 
Although the Quran is not basically a book dedicated to scientific issues, we realized from above that it contains scientific facts that have only been discovered recently through the advancement of technology and scientific knowledge. These scientific facts are a few of many clear signs of Allah Almighty. They prove that the Quran is the word of all-knowing all-wise Allah Almighty and Allah Almighty is the only one that merits to be worshiped.
