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

(51) Thus does Allah set a seal on the hearts of those who do not know.

(52) And were every tree that is in the earth (made into) pens and the sea (to supply it with ink), with seven more seas to increase it, the words of Allah would not come to an end; surely Allah is Mighty, Wise.

(53) Do you not see that the ships run on in the sea by Allah's favor that He may show you of His signs? Most surely there are signs in this for every patient endurer, grateful one.

(54) And when the hypocrites and those in whose hearts was a disease began to say: Allah and His Apostle did not promise us (victory) but only to deceive.

(55) O wives of the Prophet! you are not like any other of the women; If you will be on your guard, then be not soft in (your) speech, lest he in whose heart is a disease yearn; and speak a good word.

(56) If the hypocrites and those in whose hearts is a disease and the agitators in the city do not desist, We shall most certainly set you over them, then they shall not be your neighbors in it but for a little while;

(57) And the two seas are not alike: the one sweet, that subdues thirst by its excessive sweetness, pleasant to drink; and the other salt, that burns by its saltness; yet from each of them you eat fresh flesh and bring forth ornaments which you wear; and you see the ships cleave through it that you may seek of His bounty and that you may be grateful.

(58) On that day We will set a seal upon their mouths, and their hands shall speak to Us, and their feet shall bear witness of what they earned.

(59) Those who dispute concerning the communications of Allah without any authority that He has given them; greatly hated is it by Allah and by-those who believe. Thus does Allah set a seal over the heart of every proud, haughty one.

(60) Or do they say: He has forged a lie against Allah? But if Allah pleased, He would seal your heart; and Allah will blot out the falsehood and confirm the truth with His words; surely He is Cognizant of what is in the breasts.
