Allah; for they worship Him in a manner for which He has sent down no authority and which neither the Book nor the Sunnah has prescribed. As Allah’s close friend, peace be upon him, said when debating the polytheists, after they disputed with him and sought to frighten him with their gods:

“How should I fear what you associate with Allah, while you do not fear that you have associated with Allah that for which He has sent down no authority to you? Which of the two parties has more right to security, if you know?”

“The mosques belong to Allah, so do not invoke anyone alongside Allah.”
