stayed
in Edition Clear Qur'an by Talal Itani / Al-Kahf (The Cave)

18:19Even so, We awakened them, so that they may ask one another. A speaker among them said, “How long have you stayed?” They said, “We have stayed a day, or part of a day.” They said, “Your Lord knows best how long you have stayed.” “Send one of you to the city, with this money of yours, and let him see which food is most suitable, and let him bring you some provision thereof. And let him be gentle, and let no one become aware of you.”

18:25And they stayed in their cave for three hundred years, adding nine.

18:26Say, “God knows best how long they stayed.” His is the mystery of the heavens and the earth. By Him you see and hear. They have no guardian apart from Him, and He shares His Sovereignty with no one.
