Abdullah ibn Mas'ud reported: The Prophet, peace and blessings be upon him, made a statement and I made another in his presence. The Prophet said, "Whoever dies while calling upon a partner besides Allah will enter the Hellfire." I said, "Whoever dies without calling upon a partner besides Allah will enter Paradise."
