The Sea and its Purpose - البحر

"Allah is the one who has subjected the sea for you so that ships may sail upon it by His command, and that you may seek his bounty, and that perhaps you will be grateful"

"الله الذي سخر لكم البحر لتجري الفلك فيه بأمره و لتبتغوا من فضله و لعلكم تشكرون"

Surah Al-Jathiya 45:12 سورة الجاثية
