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.

Prophethood is a sublime status granted only to those who are chosen. A prophet deals with the heart and souls of humans; it is, therefore, a delicate matter to believe in the one who claims prophethood. Hence, there should be a sign that lets people recognize a real prophet from a fake one; that's "miracle." A "miracle" is an extraordinary act or event that no other human, from the first to the last, can perform it or cause it to happen, except a prophet. It can be neither explained by natural or scientific laws. For Prophet Muhammad (PBUH&HP), the Quran is known as an everlasting miracle that is the most outstanding of Prophet's (PBUH&HP) miracles. The question is: why the Quran is considered as a miracle? Let's find out the reasons.

1. The Quran Is Unique in Style and Inimitable

The Quran is revealed with great eloquence and fluency to convey the message. Precise, poetic, targeted, and meaningful terms used in the Quran are such that no weakness of expression can be found in any of its Ayats. In fact, the words are chosen such that they express the desired meaning in the best way possible (Fasaha) with the minimum usage of words (Balaqa). And, these are features that scholars of Arab literature have noticed in every chapter of the Quran [1]. 

What makes the Quran a miracle in this regard is that, until the present, no one has been able (and no one will be able) to bring even one short Surah similar to that of this holy book. A Surah that could express the highest scientific facts in simple, comprehensible words and describes different aspects of a scientific matter as clearly as possible. This is an issue that has already been addressed in the Quran: "And if you are in doubt concerning what We have sent down to Our servant, then bring a Surah like it, and invoke your helpers besides Allah, should you be truthful." (2:23). There is no historical account of those who succeeded in defeating this claim of the Quran. If there existed any, those who have always challenged the origin of the Quran should have recorded it. 

2. The Quran has been Brought by a Prophet Who Was Uninstructed (Ummi)

According to both historical records and the Quran, Prophet Muhammad (PBUH&HP) was Ummi before he was chosen as a messenger of Allah Almighty; he hadn't been taught by any teacher to read and write 1]. "You were not able to read or write before the Quran was revealed to you; however, the followers of falsehood would have tried to confuse the matter" (29:48). Therefore, the Quran that its words are in extreme eloquence and fluency and reveal sophisticated concepts cannot be Prophet's (PBUH&HP) word. Hence, it is a divine work gained through revelation, a "miracle." 

3. Scientific Facts Revealed by the Quran 

The Quran is not a book of science or a specialized book, nor has it aimed to concentrate on scientific facts. However, these kinds of information are stated in the Quran to demonstrate the wonders of creation and Allah Almighty's glory. 
In this regard, the creation of humans is described in detail in the Quran (23:12-14). In the first step, the human being was fashioned from clay. Other measures include the creation of man from spurting water, a drop of semen, the sperm fashioned into an embryo, this embryo fashioned into a shapeless lump of flesh. From the lump of flesh, fashioned bones, clothed the bones with flesh and then created the consanguinity and affinity [2].

The movement of the earth is another fact mentioned in the Quran: "It is Allah who raised the heavens without any pillars that you see" (13:2). In this verse, it is mentioned that there exist invisible supports that raise up the heavens. These supports are now referred to as the gravitational and other unseen forces in the universe. This scientific fact that is valid today was unknown in that era, and even one thousand years later when Galileo explained this fact and was sentenced to death. That's why it is not explicitly stated in the Quran; otherwise, it would have been banned [1].

4. Accurate Predictions 

Some accurate predictions are among the verses of the Quran. This proves that it has been descended from an absolutely knowing source that can report the unseen.

As an example, in the time of Prophet Muhammad (PBUH&HP), Mecca was controlled by polytheists for a while. They did not let Muslims enter the city and do the Hajj rituals. Then, Prophet (PBUH&HP) dreamed that he succeeded in performing Hajj with his companions. This was confirmed in an Ayah: "Certainly Allah has fulfilled His Apostle's vision in all truth: You will surely enter the Sacred Mosque, God willing, in safety, with your heads shaven or hair cropped, without any fear." (48:27). In the next year, this dream came true. 

In another case, the Quran has predicted that: "Byzantium has been vanquished in a nearby territory, but following their defeat, they will be victors in a few years." (30: 2-4). Some years later, both predictions came true. 

From what has been discussed above, it can be deduced that the Quran cannot be written by a human being. It is undoubtedly from a superior all-knowing all-wise source, which is Allah Almighty. Consequently, the Quran can be considered as one of Prophet Muhammad's (PBUH&HP) miracles, the greatest one, of course.
