Appears 4 times in the Quran. (Root: كهف)
  1. Or, do you think that the Fellows of the Cave and the Inscription were of Our wonderful signs?

  2. When the youths sought refuge in the cave, they said: Our Lord! grant us mercy from Thee, and provide for us a right course in our affair.

  3. So We prevented them from hearing in the cave for a number of years.

  4. And when you forsake them and what they worship save Allah, betake yourselves for refuge to the cave; your Lord will extend to you largely of His mercy and provide for you a profitable course in your affair.
