An-Nahl · 16:14

14. He, may He be glorified, is the One Who subjugated the sea for you and enabled you to travel on it and to extract what is in it, so that you can eat the fresh and soft meat of the fish that you catch and that you can extract from it jewellery that you and your wives can wear such as pearls and coral. You see the ships splitting the waves of the ocean and you travel on these ships in search of Allah's bounty in the form of profit you gain from trade. All of this is for you to be grateful to Allah for the favours He has given you and to worship Him alone.
