I have come across a book about reciting Surath Al Kahf on the day of Jummah. The author's name is Dr. Abdullah bin Fawzaan bin Saalih al Fawzaan.
The name suggests that he is a grand son of Ash Shaikh Saalih Al Fawzaan (Hafidhahullahu Tha'alaa) Allahu A'lam.
Therefore I would like to know about him. If any student of knowledge has information about him, let him share with us. Jazakumullahu Khairan.
