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

(21) And as for those in whose hearts is a disease, it adds uncleanness to their uncleanness and they die while they are unbelievers.

(22) He it is Who makes you travel by land and sea; until when you are in the ships, and they sail on with them in a pleasant breeze, and they rejoice, a violent wind overtakes them and the billows surge in on them from all sides, and they become certain that they are encompassed about, they pray to Allah, being sincere to Him in obedience: If Thou dost deliver us from this, we will most certainly be of the grateful ones.

(23) Then did We raise up after him apostles to their people, so they came to them with clear arguments, but they would not believe in what they had rejected before; thus it is that We set seals upon the hearts of those who exceed the limits.

(24) And We made the children of Israel to pass through the sea, then Firon and his hosts followed them for oppression and tyranny; until when drowning overtook him, he said: I believe that there is no god but He in Whom the children of Israel believe and I am of those who submit.

(25) They said: By Allah! you will not cease to remember Yusuf until you are a prey to constant disease or (until) you are of those who perish.

(26) Yielding its fruit in every season by the permission of its Lord? And Allah sets forth parables for men that they may be mindful.

(27) Allah is He Who created the heavens and the earth and sent down water from the clouds, then brought forth with it fruits as a sustenance for you, and He has made the ships subservient to you, that they might run their course in the sea by His command, and He has made the rivers subservient to you.

(28) And He it is Who has made the sea subservient that you may eat fresh flesh from it and bring forth from it ornaments which you wear, and you see the ships cleaving through it, and that you might seek of His bounty and that you may give thanks.

(29) These are they on whose hearts and their hearing and their eyes Allah has set a seal, and these are the heedless ones.

(30) Your Lord is He Who speeds the ships for you in the sea that you may seek of His grace; surely He is ever Merciful to you.
