Quranic Miracle; the seas do not mix

Peace be upon you all.

In Islam, there is no conflict between faith in God and modern scientific knowledge. Indeed, for many centuries during the Middle Ages, Muslims led the world in scientific inquiry and exploration. The Qur'an itself, revealed 14 centuries ago, is filled with scientific facts and imagery that are supported by modern findings. Please note that the Quran is a book for guidance and signs.

The Qur'an instructs Muslims to "contemplate the wonders of creation" (Qur'an 3:191). The entire universe, which was created by Allah (swt), follows and obeys His laws. Muslims are encouraged to seek knowledge, explore the universe, and find the "Signs of Allah (swt)" in His creation. Allah (swt) says:

"Behold! In the creation of the heavens and the earth;
in the alternation of the night and the day;
in the sailing of ships through the ocean, for the profit of mankind;
in the rain which Allah sends down from the skies,
and the life which He gives therewith to an earth that is dead;
in the beasts of all kinds that He scatters through the earth;
in the change of the winds,
and the clouds which they trail like their slaves between the sky and the earth;
here indeed are Signs for a people that are wise"
(Qur'an 2:164)

The seas not mingling with one another
One of the properties of seas that has only recently been discovered is related in a verse of the Qur'an as follows:

He has let loose the two seas, converging together, with a barrier between them they do not break through. (Qur'an, 55:19-20)

This property of the seas, that is, that they meet and yet do not intermix, has only very recently been discovered by oceanographers. Because of the physical force called "surface tension," the waters of neighbouring seas do not mix. Caused by the difference in the density of their waters, surface tension prevents them from mingling with one another, just as if a thin wall were between them.

It is interesting that, during a period when there was little knowledge of physics, and of surface tension, or oceanography, this truth was revealed in the Qur'an.
