Abu al-Tahir Ahmad ibn 'Amr ibn Sarh narrated to me: Ibn Wahb informed us, from Ibn Jurayj, from Ibn Abi Mulaykah, from Ibn 'Abbas, that the Prophet, peace and blessings be upon him, said: "If people were given [judgment] based on their claims, some people would claim the blood and property of others, but the oath is upon the one against whom the claim is made."
