Shaykh ibn ‘Uthaymeen, [may Allāh bestow mercy upon him], said: “Reciting Surah al-Kahf on Friday is commendable, carrying inherent virtue. Whether recited from the Qur’ān or memory, there is no difference. This auspicious day and its blessings extend from dawn to sunset, and if recited post-Friday prayer, one secures the associated rewards.” Majmū’ Fatāwa wa Rasāil Fadeelat ush-Shaykh Muhammad bin Sālih al-‘Uthaymeen [may Allāh have mercy on him],16/143.
