Seas are mentioned in the Quran in these verses:

[25:53] He is the One who merges the two seas; one is fresh and palatable, while the other is salty and undrinkable. And He separated them with a formidable, inviolable barrier (evaporation).

[35:12] The two seas are not the same; one is fresh and delicious, while the other is salty and undrinkable. From each of them you eat tender meat, and extract jewelry to wear. And you see the ships sailing through them, seeking His provisions, that you may be appreciative.

[55:19] He separates the two seas where they meet.
