Musnad Ahmad 26:262

Aswad ibn Amir narrated to us, Abu Bakr informed us, from Asim, from Abu Wa'il, who said: Abdullah said: I heard the Messenger of Allah, peace and blessings of Allah be upon him, say: "Whoever sets up a rival to Allah, Allah will place him in the Fire." And he said: And another thing I say, which I did not hear from him: Whoever dies not setting up a rival to Allah, Allah will admit him into Paradise. And indeed, these prayers are expiations for what is between them, as long as the major sins are avoided.
