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

(61) Then seest thou such a one as takes as his god his own vain desire? Allah has, knowing (him as such), left him astray, and sealed his hearing and his heart (and understanding), and put a cover on his sight. Who, then, will guide him after Allah (has withdrawn Guidance)? Will ye not then receive admonition?

(62) And among them are men who listen to thee, but in the end, when they go out from thee, they say to those who have received Knowledge, "What is it he said just then?" Such are men whose hearts Allah has sealed, and who follow their own lusts.

(63) Those who believe say, "Why is not a sura sent down (for us)?" But when a sura of basic or categorical meaning is revealed, and fighting is mentioned therein, thou wilt see those in whose hearts is a disease looking at thee with a look of one in swoon at the approach of death. But more fitting for them-

(64) Or do those in whose hearts is a disease, think that Allah will not bring to light all their rancour?

(65) So We took him and his forces, and threw them into the sea; and his was the blame.

(66) And His are the Ships sailing smoothly through the seas, lofty as mountains:

(67) But for such as fear the time when they will stand before (the Judgment seat of) their Lord, there will be two Gardens-

(68) Whose season is not limited, nor (supply) forbidden,

(69) "Indeed ye shall drink like diseased camels raging with thirst!"

(70) That is because they believed, then they rejected Faith: So a seal was set on their hearts: therefore they understand not.
