(Regarding) reading surah Kahaf on the day of Jummah, is it favored to read it continuously, and is there anything wrong if he divides it on this day?
If you stop at your statement ‘favored’, then yes it is favored.
However is it allowed to recite it intervals?
If it is not easy to recite it continuously. This is because the origin is [to recite it] continuously”.
