The word(s) "sea" appears 99 time(s) in 90 verse(s) in Quran in Mohsin Khan translation.

(81) And by the sea kept filled (or it will be fire kindled on the Day of Resurrection).

(82) In a seat of truth (i.e. Paradise), near the Omnipotent King (Allah, the One, the All-Blessed, the Most High, the Owner of Majesty and Honour).

(83) He has let loose the two seas (the salt and fresh water) meeting together.

(84) And His are the ships going and coming in the seas, like mountains.

(85) Whose supply is not cut off (by change of season), nor are they out of reach,

(86) That is because they believed, and then disbelieved; therefore their hearts are sealed, so they understand not.

(87) And We have set none but angels as guardians of the Fire. And We have fixed their number (19) only as a trial for the disbelievers, in order that the people of the Scripture (Jews and Christians) may arrive at a certainty [that this Qur'an is the truth as it agrees with their Books regarding the number (19) which is written in the Taurat (Torah) and the Injeel (Gospel)] and that the believers may increase in Faith (as this Qur'an is the truth), and that no doubt may be left for the people of the Scripture and the believers, and that those in whose hearts is a disease (of hypocrisy) and the disbelievers may say: "What Allah intends by this (curious) example ?" Thus Allah leads astray whom He wills and guides whom He wills. And none can know the hosts of your Lord but He. And this (Hell) is nothing else than a (warning) reminder to mankind.

(88) And when the seas become as blazing Fire or overflow.

(89) And when the seas are burst forth.

(90) They will be given to drink of pure sealed wine.
