What is the ruling on reciting the same verses in every Friday prayer or any other prayer?

There is no harm in repeating specific surahs and verses in every Friday prayer, as long as the worshiper does not believe it to be a Sunnah or obligatory. In fact, it may be a Sunnah if it aligns with what the Messenger of Allah, peace and blessings be upon him, regularly observed, such as his recitation of Surat Al-A'la and Al-Ghashiyah or Al-Jumu'ah and Al-Munafiqoon on Fridays, and Al-Sajdah and Al-Insan in the Fajr prayer on Friday. It is disliked to persistently observe something that the Messenger of Allah, peace and blessings be upon him, did not persistently observe.
