Is it permissible to perform a good deed through shaykhs to bring hearts together, such as making a husband love his wife?

If the intention behind seeking love between spouses is to go to those who claim to know the unseen, such as charlatans and sorcerers, to write satanic incantations, then this is forbidden, and the one who does it is in grave danger. Their prayers will not be accepted for forty nights, and if they believe these individuals, they have disbelieved in what was revealed to Muhammad, peace and blessings be upon him. However, if the intention is to seek prayers from someone known for their goodness and righteousness, there is no harm in that, as it is a permissible form of seeking intercession.
