The Water of the Two Seas Never Merge

In the Holy Qur’an, Ershad is saying,
اِنَّ فِىْ خَلْقِ السَّمٰوٰتِ وَالْاَرْضِ وَاخْتِلَافِ الَّيْلِ وَالنَّهَارِ لَاٰيٰتٍ لِّاُولِى الْاَلْبَابِ ۚۖ
“Surely there are signs for the wise between the creation of the heavens and the earth and the evolution of night and day.” (Surah Ale Imran: 190).
Regarding the description of this miracle, Allah Ta’ala said,
وَهُوَ الَّذِىْ مَرَجَ الْبَحْرَيْنِ هٰذَا عَذْبٌ فُرَاتٌ وَّهٰذَا مِلْحٌ‌ اُجَاجٌ ۚ وَجَعَلَ بَيْنَهُمَا بَرْزَخًا وَّحِجْرًا مَّحْجُوْرًا
“He is the One who made the two seas flow in parallel. One is sweet and thirst quenching and the other is salty and tasteless. And between the two there is a gap and an impenetrable wall.” (Surah Furqan: 53).
مَرَجَ الْبَحْرَيْنِ يَلْتَقِيٰنِۙ
بَيْنَهُمَا بَرْزَخٌ لَّا يَبْغِيٰنِ‌ۚ
“Comes elsewhere, ‘he said, flowing two seas side by side. There is a barrier (wall) between them which they do not cross.” (Surah Rahman: 19-20).
It is narrated in the Qur’an,
جَمَلَ الْأْأَرَضَ وَلَا يَع للَمُونَ جَجَرْا
Regarding the description of obstacles, the Holy Qur’an says, “Who is the barrier between the two seas? So is there a god with God? Basically most of them don’t know.” (Surat an-Naml: 61)
Renowned French oceanographer Jack V Costa. His contribution to various discoveries of the sea floor is undeniable. He has done extensive research on the confluence of the two seas. He realized in his research that the Roman Sea and the Atlantic Ocean were completely different from each other in terms of chemical properties and dimensions. He conducted research at the confluence of two seas in Gibraltar to see for himself. He saw a freshwater fountain overflowing from the north shore of Gibraltar (Marukesh) and the south shore (Spain). This waterfall moves rapidly through both seas at 450 fine angles and acts as a dam, taking the shape of a comb tooth. As a result, the waters of the Roman Sea and the Atlantic Ocean do not merge. Later he was recited the verse narrated in the Qur’an. He saw that his research was in complete agreement with the information given in the Qur’an. Jack V. Costa thought that illiterate people like Muhammad (pbuh) 1400 years ago could not write this information in the Qur’an by observing the bottom of the sea. So how did this great information about marine science come in the Qur’an? Surely the Qur’an is a book of divine truth. It is not man-made. Jack V Costa became a Muslim. Such miracles of the Holy Qur’an have always been proven. Allah Says in Quran:
سَنُرِيهِمْ آيَاتِنَا فِي الآفَاقِ وَفِي أَنفُسِهِمْ حَتَّى يَتَبَيَّنَ لَهُمْ أَنَّهُ الْحَقُّ أَوَلَمْ يَكْفِ بِرَبِّكَ أَنَّهُ عَلَى كُلِّ شَيْءٍ شَهِيدٌ
“We will soon show them Our signs in the Universe and in themselves,
until it will become manifest to them that it is the truth.” (Holy Quran, 41:53)
وَسَخَّرَ لَكُم مَّا فِي السَّمَاوَاتِ وَمَا فِي الْأَرْضِ جَمِيعاً مِّنْهُ إِنَّ فِي ذَلِكَ لَآيَاتٍ لَّقَوْمٍ يَتَفَكَّرُونَ
“And He has subjected to you [Sayyidina Mahmood (saws)], as from Him, all that is in the heavens and on earth: Behold, in that are Signs indeed for those who reflect [Contemplate and Meditate].” ( Holy Quran, 45:13)
مَرَ‌جَ الْبَحْرَ‌يْنِ يَلْتَقِيَانِ ﴿١٩ بَيْنَهُمَا بَرْ‌زَخٌ لَّا يَبْغِيَانِ ﴿٢٠ فَبِأَيِّ آلَاءِ رَ‌بِّكُمَا تُكَذِّبَانِ ﴿٢١
“He has made the two seas to flow freely (so that) they meet together.” (Quran, 55:19)
“Between them is a barrier which they cannot pass.” (Quran, 55:20)
“So which of the favors of your Lord will you deny?”(Quran, 55:21)
سَنُرِيهِمْ آيَاتِنَا فِي الآفَاقِ وَفِي أَنفُسِهِمْ حَتَّى يَتَبَيَّنَ لَهُمْ أَنَّهُ الْحَقُّ أَوَلَمْ يَكْفِ بِرَبِّكَ أَنَّهُ عَلَى كُلِّ شَيْءٍ شَهِيدٌ
“We will soon show them Our signs in the Universe and in themselves, until it will become manifest to them that it is the truth.” (Holy Quran, 41:53)
وَهُوَ الَّذِي مَرَجَ الْبَحْرَيْنِ هَذَا عَذْبٌ فُرَاتٌ وَهَذَا مِلْحٌ أُجَاجٌ وَجَعَلَ بَيْنَهُمَا بَرْزَخاً وَحِجْراً مَّحْجُوراً
“And it is He Who has let free the two seas to flow: One palatable and sweet, and the other salty and bitter. And He has made a barrier between them and an area forbidden (to pass) and isolated.” (Holy Quran 25:53)
In Surat al-Furqan, Allah mentions that in addition to the barrier (Barzakh), (which is also mentioned in Surat ar-Rahman), there is a Hijran Mahjura
حِجْراً مَّحْجُوراً which means a completely separated area, partitioned off and inaccessible.
“He has let free the two bodies of flowing water, meeting together: Between them is a Barrier which they do not transgress.” (Al-Qur’an Rahman 55:19-20)
When the water from one sea enters the other sea, it loses its distinctive characteristic and becomes homogenized with the other water. In a way this barrier serves as a transitional homogenizing area for the two waters. This phenomenon is also mentioned in the following verse of the Qur’an:
“And made a separating bar between the two bodies of flowing water?” (Al-Qur’an Naml 27:61)
“It is He Who has let free the two bodies of flowing water: one palatable and sweet, and the other salty and bitter; yet has He made a barrier between them, to be passed.” (Al-Qur’an Furkan 25:53)
