Modern Science has discovered that in the places where two different seas meet up, there is a barrier between them. This barrier divides the two seas so that each sea has its own temperature, salinity, and density. For example, Mediterranean Sea water is warm, saline and less dense, compared to Atlantic Ocean water. When Mediterranean Sea water enters the Atlantic, it moves several hundred kilometers into the Atlantic at a depth of about one kilometer with its own warm, saline and less dense characteristics, because of the barrier that distinguishes between them. Although there are large waves, strong currents, and tides in these seas, they do not mix or transgress this barrier.

The Quran preceded the modern science and said that there is a barrier between two seas that meet and that they do not transgress.

The Meeting of Two Seas in the Bible:
The Meeting of Two Seas or even the meeting of two rivers is not mentioned in the Old Testament. It is only mentioned once in the New Testament.

Where two seas met, they ran the ship aground; and the forepart stuck fast, and remained unmovable, but the hinder part was broken with the violence of the waves.

Acts 27:38-41

38 And when they had eaten enough, they lightened the ship, and cast out the wheat into the sea.
39 And when it was day, they knew not the land: but they discovered a certain creek with a shore, into the which they were minded, if it were possible, to thrust in the ship.
40 And when they had taken up the anchors, they committed themselves unto the sea, and loosed the rudder bands, and hoised up the mainsail to the wind, and made toward shore.
41 And falling into a place where two seas met, they ran the ship aground; and the forepart stuck fast, and remained unmovable, but the hinder part was broken with the violence of the waves.

The Meeting of Two Seas in the Quran:

The Barrier between the Fresh and salt Waters when they meet

The Quran talks about the divider between fresh and salt water, it mentions the existence of "a forbidding partition" with the barrier.
In addition, the Quran says that there are two types of Pearls, the Freshwater and Saltwater Pearls

Surah 25:53

It was he who let forth the two seas, this one is palatably sweet and this salt, a bitter taste, and he set a barrier between them, and a refuge which is forbidden.

Surah 55:19- 28

[19] He has let free the two bodies of flowing water (salt and fresh), meeting together:

[20] Between them is a barrier which they do not transgress:

[21] Then which of the favors of your lord will ye deny?

[22] Out of them come pearls and coral:

[23] Then which of the favors of your lord will ye deny?

[24] Also, his are the ships displayed upon the sea, like banners.

[25] Then which of the favors of your lord will ye deny?

[26] All that live on it will perish.

[27] And there will endure for ever the person of your lord, the lord of glory and honor

[28] Then which of the favors of your lord will ye deny?

In addition, the Quran mentioned that there is a barrier between two seas that meet and that they do not transgress.
The Quran uses the scientific information in order that you might answer this important theological question:
Is there a god with Allah?

Surah 27:60- 61

[60] nay, he who created the heavens and the earth, and sent water from the sky for you and caused gardens to grow full of beauty of which its tree you could never grow, is there a god with Allah? no, but they are a nation who set up equals with him!

[61] Or, who made the earth a resting place, and made in it rivers, and raised on it mountains and placed between the two seas a barrier. is there a god with Allah? Nay! Most of them do not know!

A Historical event that is not mentioned in the Bible.
Moses and the blessed knowledgeable man:
Moses went to the junction where the two seas meet in order to see the blessed knowledgeable man. Moses wanted to learn from him. This story is not mentioned in the Bible.

The revival of the cooked fish is the sign!

Surah 18:60-69

[60] When Moses said to his attendant: 'I will not give up until i reach the point where the two seas meet even though I should go on for many years. '

[61] So when they had reached the junction where the two seas met, they forgot their fish, which made its way burrowing into the sea.
(The fish went alive after it had been cooked and ready to be eaten! and this was the sign for the place where Moses will meet the man).
[62] And when they had gone further, he said to his assisting attendant; 'bring us our meal; we have suffered much fatigue and worn out from our journey.

[63] he said: did you see when we took refuge on the rock then I forgot the fish, and nothing made me forget to speak of it but the Satan, and it took its course through the sea in a marvelous way!"

[64] 'This is what we have been seeking! 'Said he (Moses, because it was the sign), and they retraced their footsteps

[65] And they found one of our worshipers to whom we had given from our mercy, and to whom we had taught knowledge of ours.

[66] Moses said to him: 'may I follow you so that you can teach me of that you have learned of righteousness? '

[67] He said: surely you cannot have patience with me

[68] And how can you have patience in that of which you have not got a comprehensive knowledge?

[69] He (Moses) said: 'if Allah wills, you shall find me patient, I shall not disobey your order. '

This story is very interesting, although it is not cited in the Bible.

Back to the main topic of my series of articles (1- 78); this is my question to you smart readers: "Is the Quran quoted from the Bible "? And which book preceded the modern Sciences?
