Is the recitation of Surat Al-Kahf during the Fajr and Isha prayers on Friday considered an innovation (bid'ah)?

Reciting Surat Al-Kahf is prescribed on Fridays. However, there is no evidence for the legitimacy of reciting it in Fajr and Isha prayers and consistently doing so. What is recommended is reciting Surat Al-Sajdah and Surat Al-Insan in Fajr on Friday, and reciting the surahs that the Prophet taught to Mu'adh for Isha prayer. Continuously reciting a specific surah (definition) at a specific time may fall under innovation (bid'ah). Therefore, it is advised to abandon the practice of consistently reciting Surat Al-Kahf in Fajr and Isha on Fridays and adhere to the guidance of the Prophet, peace and blessings be upon him.
