Scientfic discoveries recently discovered but was written in the quran 1400 years ago!

Modern Science has discovered that in the places where two different seas meet, there is a barrier between them. This barrier divides the two seas so that each sea has its own temperature, salinity, and density.
[Principles of Oceanography - Davis, pp. 92-93]


For example, Mediterranean Sea water is warm, saline and less dense, compared to Atlantic Ocean water. When Mediterranean Sea water enters the Atlantic over the Gibraltar sill, it moves several hundred kilometers into the Atlantic at a depth of about 1,000 meters with its own warm, saline and less dense characteristics.
The Mediterranean water stabilizes at this depth.
[Principles of Oceanography p. 93]


The Mediterranean Sea water as it enters the Atlantic over the Gibraltar sill with its own warm, saline and less dense characteristics, because of the barrier that distinguishes between them. Temperatures are in degrees Celsius (C).

Even in depths (indicated here by darker colors) up to 1,400 meters and at distances ranging from a minus -100 to +2,500 meters, we find that both bodies of water maintain their individual temperatures and salinity.

Although there are large waves, strong currents, and tides in these seas, they do not mix or transgress this barrier.

The Holy Quran mentioned that there is a barrier between two seas that meet and that they do not transgress. God said:

He has let free the two seas meeting to gather. There is a barrier between them. They do not transgress.

[Noble Quran 55:19-20]


But when the Quran speaks about the divider between fresh and salt water, it mentions the existence of "a forbidding partition" with the barrier.

God said in the Quran:

He is the one who has let free the two bodies of flowing water, one sweet and palatable, and the other salty and bitter. And He has made between them a barrier and a forbidding partition.
[Noble Quran 25:53]


On may ask, why did the Quran mention the partition when speaking about the divider between fresh and salt water, but did not mention it when speaking about the divider between the two seas?
Modern science has discovered that in estuaries, where fresh (sweet) and salt water meet, the situation is somewhat different from what is found in places where two seas meet. It has been discovered that what distinguishes fresh water from salt water in estuaries is a "pycnocline zone with a marked density discontinuity separating the two layers."
[Oceanography p. 242]


This partition (zone of separation) has a different salinity from the fresh water and from the salt water
[Oceanography p. 244 and Introductory Oceanography pp. 300-301]


This information has been discovered only recently using advanced equipment to measure temperature, salinity, density, oxygen dissolubility, etc. The human eye cannot see the difference between the two seas that meet, rather the two seas appear to us as one homogeneous sea. Likewise the human eye cannot see the division of water in estuaries into the three kinds: the fresh water, the salt water, the partition (zone of separation).

In the Holy Quran, God speaks about the stages of man's embryonic development, 1,400 years before modern day scientists 'discovered' important information on creation of man and his development:

We created man from an extract of clay. Then We made him as a drop in a place of settlement, firmly fixed. Then We made the drop into an alaqah (leech, suspended thing, and blood clot), then We made the alaqah into a mudghah (chewed-like substance)...
[Noble Quran 23:12-14]


Literally the Arabic word alaqah has 3 meanings:
leech
suspended thing
blood clot

1. "In comparing a leech to the embryo at the alaqah stage, we find similarity between the two."
[The Developing Human p.8]
.
"Also, the embryo as this stage obtains nourishment from the blood of the mother, similar to the leech which feeds on the blood of others."
[Human Development as Described in Quran and Sunnah p.36]
.

2. The second meaning of the word alaqah is 'suspended thing'. The suspension of the embryo, during the alaqah stage, in the womb of the mother very appropriately fits this description.

3. The third meaning of the word alaqah is 'blood clot'. We find that the external appearance of the embryo and its sacs during the alaqah stage is similar to that of a blood clot. This is due to the presence of relatively large amounts of blood present in the embryo during this stage. Also during this stage the blood in the embryo does not circulate until the end of the third week. So the embryo at this stage is like a clot of blood.

By examining a diagram of the primitive cardiovascular system in an embryo during the alaqah stage we would notice the external appearance of the embryo and its sacs is similar to that of a blood clot due to the presence of relatively large amounts of blood present in the embryo
[The Developing Human, p. 65]


So the three meanings of the word alaqah correspond accurately to the descriptions of the embryo at the alaqah stage.

The next stage mentioned in the verse is the mudghah stage. The Arabic word mudghah means "chewed-like substance." If one were to take a piece of gum and chew it in his mouth, and then compare it with the embryo at the mudghah stage, we would conclude that they would be almost identical because of the somites at the back of the embryo that 'somewhat resemble teeth marks in a chewed substance.'

How could Muhammad (peace be upon him) have possibly known all this 1,400 years ago when scientists have only recently discovered this using advanced equipment and powerful microscopes which did not exist at that time? Hamm and Leeuwenhoek were the first scientists to observe human sperm cells using an improved microscope in 1677 A.D. (more than 1,000 years after Muhammad, peace be upon him]. They mistakenly thought that the sperm cell contained a miniature preformed human being that grew when it was deposited in the female genital tract
[The Developing Human, p.9]


Professor Keith Moore is one of the world's prominent scientists in the fields of anatomy and embryology and is the author of the book entitled the "Developing Human", which has been translated into eight languages. This book is considered a scientific reference work and was chosen by a special committee in the United States as the best book authored by on person. Dr. Keith Moore is a Professor of Anatomy and Cell Biology at the University of Toronto, Toronto, Canada. In 1984, he received the most distinguished award presented in the field of anatomy in Canada, the J.C.B. Grant Award from the Canadian Association of Anatomists. He has directed many international associations, such as the Canadian and American Association of Anatomists and the Council of the Union of Biological Sciences.

In 1981, during the Seventh Medical Conference in Dammam, Saudi Arabia, Professor Moore said; "It has been a great pleasure for me to help clarify statements in the Quran about human development. It is clear to me that these statements must have come to Muhammad from God, or Allah, because almost all of this knowledge was not discovered until many centuries later. This proves to me that Muhammad must have been the messenger of God, or Allah [The reference for this statement is on 'This is the Truth' (video tape). For a copy of this video tape please contact us].

Consequently, Professor Moore was asked the following question, "Does this mean that you believe that the Quran is the Word of God?" He replied; "I find no difficulty in accepting this."

During one conference, Professor Moore stated, "... because the stagein of human embryos is complex, owing to the continuous process of change during development, it is proposed that a new system of classification could be developed using the terms mentioned in the Quran and the Sunnah (sayings of Muhammad, peace be upon him). The proposed system is simple, comprehensive, and conforms with present embryological knowledge. The intensive studies of the Quran and Hadith (reliably transmitted sayings and reports of Prophet Muhammad, peace be upon him) in the last four years have revealed a system of classifying human embryos that is amazing since it was recorded in the 7th century A.D. Although Eric Statle, the founder of the science of embryology, realized that chick embryos developed in stages from his studies of hen's eggs in the fourth century B.C., he did not give any details about these stages. As far as it is known from the history of embryology, little was known about the stagein and classification of human embryos until the twentieth century. For this reason, the descriptions of the human embryo in the Quran cannot be based on scientific knowledge in the 7th century A.D. The only reasonable conclusion is that these descriptions were revealed to Muhammad from God. He could not have known such details because he was an illiterate man with absolutely no scientific training." [This is the Truth -video tape]

This is how the Quran described mountains. God said in the Quran:

Have We not made the earth as a bed, and the mountains as pegs?
[Noble Quran 78:6-7]


Modern earth sciences have proven that mountains have deep roots under the surface of the ground and that these roots can reach several times their elevations above the surface of the ground. So the suitable word to describe mountains on the basis of this information is the word 'peg', since most of a properly set peg is hidden under the surface of the ground. The history of science tells us that the theory of mountains having deep roots was introduced only in the latter half of the nineteenth century.
[Geological Concept of Mountains p.5]


Mountains also play an important role in stabilizing the crust of the earth.
[Geological Concept of Mountains pp. 44-45]
. They hinder the shaking of the earth. God said in the Quran:

And He has set firm mountains in the earth so that it would not shake with you...
[Noble Quran 16:15]


Likewise the modern theory of plate tectonics holds that mountains work as stabilizers for the earth. This knowledge about the role of mountains as stabilizers for the earth has just begun to be understood in the framework of plate tectonics since the late 1960's
[Geological Concept of Mountains p. 5]
.

Could anyone during the time of the prophet Muhammad (peace be upon him) have known of the true shape of mountains? Could any one imagine that the solid massive mountain which he sees before him, actually extends deep into the earth and has a root, as scientists assert? A large number of books of geology when discussing mountains, only describe that part which is above the surface of the earth. This is because these books were not written by specialists in geology. However, modern geology has confirmed the truth of the Quran's verses.
