Say, “I seek refuge in the Lord of mankind. The Sovereign of mankind. The God of mankind. From the evil of the retreating whisperer — who whispers into the breasts of mankind. From among the jinn and mankind.”
Allah is the Lord of mankind. He is the one who created you and me, and made all things necessary for our sustenance on this earth.
Hence He is our King and Owner. If so, it would be absurd then to worship anyone else. We should fill our heart with love, respect and fear of Allah to a degree no one else should occupy such reverence.
