Musannaf Ibn Abi Shayba 19:863

Abu Bakr narrated to us, he said: Abu Khalid al-Ahmar narrated to us, from Abu Malik, from his father, who said: I heard the Prophet, peace and blessings of Allah be upon him, saying: "Whoever professes the oneness of Allah and disbelieves in what is worshipped besides Him, his blood and his property are inviolable, and his reckoning is with Allah."
