Abu Nu’aim (may Allah have mercy on him) says: A man or an old man, who was from among the people of Madinah, came and stayed with Masruq (may Allah have mercy on him). He said: I heard Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) saying that the Messenger of Allah (peace and blessings of Allah be upon him) said:“Whoever meets Allah in such a state that he does not associate anyone with Him, then no sin will harm him because of that deed. But whoever dies in such a state that he associates someone with Allah, then no good deed will benefit him because of that deed.”
