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

(41) And when you are firmly seated, you and those with you, in the ark, say: All praise is due to Allah who delivered us from the unjust people:

(42) Or like utter darkness in the deep sea: there covers it a wave above which is another wave, above which is a cloud, (layers of) utter darkness one above another; when he holds out his hand, he is almost unable to see it; and to whomsoever Allah does not give light, he has no light.

(43) Is there in their hearts a disease, or are they in doubt, or do they fear that Allah and His Apostle will act wrongfully towards them? Nay! they themselves are the unjust.

(44) And He it is Who has made two seas to flow freely, the one sweet that subdues thirst by its sweetness, and the other salt that burns by its saltness; and between the two He has made a barrier and inviolable obstruction.

(45) Then We revealed to Musa: Strike the sea with your staff. So it had cloven asunder, and each part was like a huge mound.

(46) Or, Who made the earth a restingplace, and made in it rivers, and raised on it mountains and placed between the two seas a barrier. Is there a god with Allah? Nay! most of them do not know!

(47) Or, Who guides you in utter darkness of the land and the sea, and Who sends the winds as good news before His mercy. Is there a god with Allah? Exalted by Allah above what they associate (with Him).

(48) So We caught hold of him and his hosts, then We cast them into the sea, and see how was the end of the unjust.

(49) Of those who divided their religion and became seas every sect rejoicing in what they had with them

(50) Corruption has appeared in the land and the sea on account of what the hands of men have wrought, that He may make them taste a part of that which they have done, so that they may return.
