sea
in Edition Clear Qur'an by Talal Itani / Al-A'raaf (The Heights)

7:100Is it not guidance for those who inherit the land after its inhabitants, that if We willed, We could strike them for their sins? And seal up their hearts, so that they would not hear?

7:101These towns—We narrate to you some of their tales. Their messengers came to them with the clear signs, but they would not believe in what they had rejected previously. Thus God seals the hearts of the disbelievers.

7:136So We took vengeance on them, and drowned them in the sea—because they rejected Our signs, and paid no heed to them.

7:138And We delivered the Children of Israel across the sea. And when they came upon a people who were devoted to some statues of theirs, they said, “O Moses, make for us a god, as they have gods.” He said, “You are truly an ignorant people.”

7:163Ask them about the town by the sea, when they violated the Sabbath. When they observed the Sabbath, their fish would come to them abundantly. But when they violated the Sabbath, their fish would not come to them. Thus We tried them because they disobeyed.
