Musnad Ahmad 26:315

Aswad ibn Amir narrated to us, Abu Bakr narrated to 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." He said: And another thing I say, which I did not hear from him: "And whoever dies not setting up a rival to Allah, Allah the Almighty and Majestic will admit him into Paradise. And these prayers are expiations for what is between them, as long as the major sins are avoided."
