The Seven Sleepers (Arabic: اصحاب الکھف aṣḥāb al kahf, "companions of the cave") of Ephesus are legendary people in a story of a group of youths who hid inside a cave outside the city of Ephesus around 250 AD, to escape a persecution. The king forced all his kingdom to worship idols and whoever did not would be killed. These men escaped as their faith in God (their belief varies by regional origin) was strong and refused to worship idols. The story is one of the many examples of the legend about a man who falls asleep and years after wakes up to find the world changed.
