Abu Malik al-Ashja'i narrates from his father that he heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever says 'La ilaha illallah' (there is no god but Allah), and disbelieves in whatever is worshipped besides Allah, Allah has made his wealth and his blood inviolable, and his reckoning is with Allah."
