Quran 18:1 — The Cave (Al-Kahf)

Praise GOD, who revealed to His servant this scripture, and made it flawless.

[18:0] In the name of God, Most Gracious, Most Merciful.

[18:2] A perfect (scripture) to warn of severe retribution from Him, and to deliver good news to the believers who lead a righteous life, that they have earned a generous recompense.
