The word(s) "sea" appears 74 time(s) in 73 verse(s) in Quran in Abdullah Yusuf Ali translation.

(51) Muhammad is not the father of any of your men, but (he is) the Messenger of Allah, and the seal of the Prophets: and Allah has full knowledge of all things.

(52) Truly, if the Hypocrites, and those in whose hearts is a disease, and those who stir up sedition in the City, desist not, We shall certainly stir thee up against them: Then will they not be able to stay in it as thy neighbours for any length of time:

(53) That Day shall We set a seal on their mouths. But their hands will speak to us, and their feet bear witness, to all that they did.

(54) They have not the power to help them: but they will be brought up (before Our Judgment-seat) as a troop (to be condemned).

(55) And they have invented a blood-relationship between Him and the Jinns: but the Jinns know (quite well) that they have indeed to appear (before his Judgment-seat)!

(56) "(Such) as dispute about the Signs of Allah, without any authority that hath reached them, grievous and odious (is such conduct) in the sight of Allah and of the Believers. Thus doth Allah, seal up every heart - of arrogant and obstinate Transgressors."

(57) What! Do they say, "He has forged a falsehood against Allah"? But if Allah willed, He could seal up thy heart. And Allah blots out Vanity, and proves the Truth by His Words. For He knows well the secrets of all hearts.

(58) In order that ye may sit firm and square on their backs, and when so seated, ye may celebrate the (kind) favour of your Lord, and say, "Glory to Him Who has subjected these to our (use), for we could never have accomplished this (by ourselves),

(59) "And leave the sea as a furrow (divided): for they are a host (destined) to be drowned."

(60) It is Allah Who has subjected the sea to you, that ships may sail through it by His command, that ye may seek of his Bounty, and that ye may be grateful.
