The word(s) "sea" appears 85 time(s) in 79 verse(s) in Quran in Muhammad Pickthal translation.

(11) To hunt and to eat the fish of the sea is made lawful for you, a provision for you and for seafarers; but to hunt on land is forbidden you so long as ye are on the pilgrimage. Be mindful of your duty to Allah, unto Whom ye will be gathered.

(12) Say: Have ye imagined, if Allah should take away your hearing and your sight and seal your hearts, Who is the Allah Who could restore it to you save Allah? See how We display the revelations unto them! Yet still they turn away.

(13) And with Him are the keys of the Invisible. None but He knoweth them. And He knoweth what is in the land and the sea. Not a leaf falleth but He knoweth it, not a grain amid the darkness of the earth, naught of wet or dry but (it is noted) in a clear record.

(14) Say: Who delivereth you from the darkness of the land and the sea? Ye call upon Him humbly and in secret, (saying): If we are delivered from this (fear) we truly will be of the thankful.

(15) And He it is Who hath set for you the stars that ye may guide your course by them amid the darkness of the land and the sea. We have detailed Our revelations for a people who have knowledge.

(16) Therefore We took retribution from them; therefore We drowned them in the sea: because they denied Our revelations and were heedless of them.

(17) And We brought the Children of Israel across the sea, and they came unto a people who were given up to idols which they had. They said: O Moses! Make for us a god even as they have gods. He said: Lo! ye are a folk who know not.

(18) Ask them (O Muhammad) of the township that was by the sea, how they did break the Sabbath, how their big fish came unto them visibly upon their Sabbath day and on a day when they did not keep Sabbath came they not unto them. Thus did We try them for that they were evil-livers.

(19) When the hypocrites and those in whose hearts is a disease said: Their religion hath deluded these. Whoso putteth his trust in Allah (will find that) lo! Allah is Mighty, Wise.

(20) They are content that they should be with the useless and their hearts are sealed, so that they apprehend not.
