Surah Al-Kahf, the eighteenth chapter of the Qur’an, holds a unique connection with Fridays. The Prophet ﷺ taught that whoever recites it on Friday will have a light that shines for him until the next Friday, guiding and protecting him. This Surah contains profound lessons from the stories of the People of the Cave, Musa (AS) with Khidr, and Dhul-Qarnayn, each highlighting faith, patience, and trust in Allah. One of its greatest secrets is the protection it grants from the fitnah of Dajjal, a trial unlike any other. Reciting Surah Al-Kahf weekly is not just a ritual but a source of guidance, protection, and spiritual light for the believer in this world of tests.
