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].

The Holy Quran is a record of the exact words of the last revelations from Allah Almighty to Prophet Muhammad (PBUH&HP). Since he was uninstructed (29:48), he recited the words to his companions, who either memorized them or wrote them down. Here are some facts about this divine Book. 

1. How Was the Holy Quran Revealed?

The Holy Quran was revealed to Prophet Muhammad (PBUH&HP) through the archangel Gabriel (Jibrail) in two forms [1]: all at once and gradually. The Holy Quran was once revealed on the night of Qadr (Laylat al Qadr): “The month of Ramaḍan is one in which the Quran was sent down” (2:185). Also, it was sent incrementally over 23 years until he passed away, which caused the faithless to object: “Why has not the Quran been sent down to him all at once?” (25:32)

2. Who Turned the Holy Quran into its Written Form?

During the life of Prophet Muhammad (PBUH&HP), the Quran was written on the skin of animals, palm’s wood, and tissue. After Prophet Muhammad (PBUH&HP) demise, there was a need to unify the written texts of the Quran into one specific Arabic dialect and to clarify the reading of the Quran. This happened in the time of the third Caliph, who ordered to collect a unique version of the diacritic the Quran, and other versions were eliminated such that he united the Muslims on one authoritative recension [2]. It should be noted that the actual version of the Quran is the one which was originally collected during the time of the Prophet Muhammad (PBUH&HP) and under his supervision. That is to say, the content of this holy book has remained undistorted since it was first revealed to Prophet Muhammad (PBUH&HP), and only its form and diacritic was unified at the time of the third Caliph. Therefore, the longer surahs are found at the beginning of the Quran and the shorter ones towards the end.

3. What Are the Other Names of the Holy Quran?

The Quran has some other names the most important of which are [3]: 

•    Al-Kitab, meaning the Book: “This is the Book. There is no doubt about it.” (2:1-2); 

•    Al-Furqan, meaning the criterion for the right and wrong since it gives Muslims some tools to differentiate between the truth and false, the lawful and unlawful: “Blessed is He who sent down the Criterion (the Furqan) to His servant that he may be a warner to all the nations.” (25:1);

•    Al-Dhikr, meaning a reminder because the Quran reminds us of Allah Almighty: “Indeed We have sent down the Reminder, and indeed We will preserve it.” (15:9).

4. What Are the Number of Ayats and Surahs of the Holy Quran?

The Quran is composed of 114 chapters, called "Surahs", and 6236 verses, called "Ayats". It is divided into 30 sections called “Joz’” and 60 sub-sections called “Hizb.” The longest surah is Baqarah and the shortest Kawthar. 

5. What Are Different Kinds of Surahs in the Holy Quran?

The surahs of the Holy Quran are divided into two groups: those revealed to Prophet Muhammad (PBUH&HP) when he lived in Mecca, called Makki, and those from after his migration to Medina, called Madani. Generally, the ayats about the Islamic axioms, such as monotheism, prophethood, and afterlife, were revealed in Mecca since the new Muslims required to get fully acquainted with these principles. The ayats about governing the Islamic society, practical principals, and details were revealed in Medina.  

6. How Are the Surahs Named? 

Every surat of the Quran has a specific title. These titles were known from the time of the Prophet Muhammad (PBUH&HP), and he was the one who introduced these titles initially. The titles were determined to represent the concept and topics discussed in that surat or a priority considered in the Quran about that surat [4].

7. Why and How Should We Respect the Holy Quran?

It is essential to treat the Quran respectfully since it is a divine revelation in every aspect. In this regard, the paper upon which the Quran is written and the Arabic words on its pages should not be touched without having performed ablutions (Wudhu). Moreover, when one is reading the Quran out loud, it is better if the listener keeps silent, listens (7:204), and thinks about the meaning of words.
