Hadith on Shirk: Must reject false gods to complete faith

Tariq ibn Ashyam reported: The Messenger of Allah, peace and blessings be upon him, said, “Whoever says there is no God but Allah, and disbelieves in what is worshiped besides Allah, his property and his life are sacred and he will be held accountable to Allah.”

In another narration, the Prophet said, “Whoever singles Allah out for worship.”
