Is reciting Surat Yusuf after Fajr prayer for forty days to facilitate marriage a Bid'ah (innovation in religion)?

There is no religious text that proves that Surah (definition) Yusuf has a special effect in facilitating marriage. Worship is based on divine command, so no attention should be paid to such claims. It is advised to supplicate to Allah Almighty frequently to be blessed with a righteous spouse.
