Is reading Soorat al-Kahf on Friday or the night before a recommended action?.
Praise be to Allaah.
There are marfoo’ ahaadeeth concerning that which support one
another and indicate that it is prescribed to read Soorat al-Kahf on
Friday.
That was proven to be narrated from Abu Sa’eed al-Khudri and
the isnaads stop with him. In an issue like this, it cannot be deemed to be
his personal opinion; rather he must have learned it from the Prophet (blessing s and peace of Allaah be upon him). End quote.
