Luqman - 31:31
Do you not see the ships sailing in the sea by the grace of Allah to show you some of His signs? In that are lessons for every patient and thankful person.
Allah has made the Sea at our disposal:
Originator/35:12
The two seas are not equal to each other. This one is fresh and sweet and soft to drink, and that one is salty and bitter. From each of them you eat fresh meat and extract jewels to wear. You will see ships splitting it, seeking His favor. Perhaps now you will give thanks.
The Table Spread/5:96
It is lawful for you to hunt the animals of the sea and to eat them. As sustenance for you and for travelers. Land hunting is forbidden to you while you are in ihram. Listen to Allah, before Whom you will be gathered.
The Most Gracious/55:19
He has released the two seas; they meet each other.
The Most Gracious/55:20
There is a barrier between them; they do not transgress and interfere with each other.
The Most Gracious/55:21
Which of the Blessings of your Lord can you deny?
The Most Gracious/55:22
Pearls and coral come out of both of them.
