The word(s) "sea" appears 83 time(s) in 79 verse(s) in Quran in Muhammad Habib Shakir translation.

(71) In the seat of honor with a most Powerful King.

(72) He has made the two seas to flow freely (so that) they meet together:

(73) And His are the ships reared aloft in the sea like mountains.

(74) That is because they believe, then disbelieve, so a seal is set upon their hearts so that they do not understand.

(75) And We have not made the wardens of the fire others than angels, and We have not made their number but as a trial for those who disbelieve, that those who have been given the book may be certain and those who believe may increase in faith, and those who have been given the book and the believers may not doubt, and that those in whose hearts is a disease and the unbelievers may say: What does Allah mean by this parable? Thus does Allah make err whom He pleases, and He guides whom He pleases, and none knows the hosts of your Lord but He Himself; and this is naught but a reminder to the mortals.

(76) And when the seas are set on fire,

(77) And when the seas are made to flow forth,

(78) They are made to quaff of a pure drink that is sealed (to others).

(79) The sealing of it is (with) musk; and for that let the aspirers aspire.
