[Machine] The Messenger of Allah ﷺ said, "The people of one religion do not inherit from the people of another religion, and the testimony of one religion does not validate the testimony of another religion, except for my Ummah (community). Their testimony is valid against others. Umar ibn Rashid is not strong, as Imam Ahmad ibn Hanbal, Yahya ibn Ma'in, and other scholars of Ahl al-Naqal (people of transmission) weakened him. Abu Abdullah al-Hafiz allowed me to narrate from him, from Abu al-Abbas, from Rabi'ah, from al-Shafi'i, that Muslim ibn Khalid informed Ibn Abi Najih, from Mujahid, that he said, 'Two just and free Muslims', meaning the saying of Allah the Most High, 'From whom you accept their testimony.'"
