Abu Huraira reported Allah's Messenger (may peace be upon him) as stating that Allah the Most High and Exalted said: I am the One, One Who does not stand in need of a partner. If anyone does anything in which he associates anyone else with Me, I shall abandon him with one whom he associates with Allah.
