The benefits of reading surah Al-Kahf will make a person get forgiveness from all his sins by Allah SWT. Because, every human being must have sin. Satan will always try to undermine faith and invite people to go astray.

As contained in HR. Abu Bakr bin Mardawaih, that Rasulullah SAW said; "Whoever reads Surah Al-Kahf on Friday, a light will emanate from under his feet to the sky, will illuminate it later on the Day of Resurrection, and his sins will be forgiven between two Fridays."
