The word(s) "seas" appears 24 time(s) in 22 verse(s) in Quran in Muhammad Pickthal translation.

(1) In their hearts is a disease, and Allah increaseth their disease. A painful doom is theirs because they lie.

(2) They ask thee, (O Muhammad), of new moons, say: They are fixed seasons for mankind and for the pilgrimage. It is not righteousness that ye go to houses by the backs thereof (as do the idolaters at certain seasons), but the righteous man is he who wardeth off (evil). So go to houses by the gates thereof, and observe your duty to Allah, that ye may be successful.

(3) They are not all alike. Of the People of the Scripture there is a staunch community who recite the revelations of Allah in the night season, falling prostrate (before Him).

(4) And thou seest those in whose heart is a disease race toward them, saying: We fear lest a change of fortune befall us. And it may happen that Allah will vouchsafe (unto thee) the victory, or a commandment from His presence. Then will they repent them of their secret thoughts.

(5) When the hypocrites and those in whose hearts is a disease said: Their religion hath deluded these. Whoso putteth his trust in Allah (will find that) lo! Allah is Mighty, Wise.

(6) But as for those in whose hearts is disease, it only addeth wickedness to their wickedness, and they die while they are disbelievers.

(7) Giving its fruit at every season by permission of its Lord? Allah coineth the similitudes for mankind in order that they may reflect.

(8) That He may make that which the devil proposeth a temptation for those in whose hearts is a disease, and those whose hearts are hardened - Lo! the evil-doers are in open schism -

(9) Is there in their hearts a disease, or have they doubts, or fear they lest Allah and His messenger should wrong them in judgment? Nay, but such are evil-doers.

(10) And He it is Who hath given independence to the two seas (though they meet); one palatable, sweet, and the other saltish, bitter; and hath set a bar and a forbidding ban between them.
