As for surah khaf this is proven by the hadeeth on the day of Friday. The rest will be an innovation if recited every jumua.

I would like to know if is ok to read certain surahs such as surah jumma, surah kehef n surah dakhaan on the eve of jumma every week? Is their recitation on a specific day proven by ahaadeeth?
