Qur'anic verses - Waters .. Sweet and Salt:

In the world taken as a whole, there are two bodies of water: (1) the great salt Ocean, and (2) the bodies of sweet water fed by rain, whether they are rivers, lakes, or springs. The drainage of the sweet water is eventually to the Ocean. Although the two bodies of water will mingle, their characteristics remain distinct as if there is a partition between them, by which they are always kept apart. The wonderful Sign is that the two bodies of water, though they pass through each other, remain distinct, with their distinct functions.

Jacques Yves Cousteau, French oceanographer, who has spent his lifetime on undersea discoveries and is considered an authority on undersea exploration has embraced Islam after his amazing undersea discovery was confirmed by the Holy Qur'an.

Cousteau was doing some undersea exploration when he discovered that within the salty sea water there where several springs of sweet palatable water.

What amazed him most was the fact that the sweet water of the springs was not mingling with the salty water of the sea. For a long time he tried to find plausible excuses for this phenomena. One day when he mentioned it to a Muslim professor who told him this phenomena simply followed God's command as clearly explained in the Holy Qur'an. He then read to Cousteau further verses from the Holy Qur'an:

And made a separating bar between the two bodies of flowing waters?
[Qur'an 27:61]

He let free the two bodies of flowing water, meeting together: Between them is a Barrier which they do not transgress.
[Qur'an 55:19-20]

Hearing this, Cousteau said that surely the Qur'an is a divine Book and embraced Islam.
