Yahya ibn Yahya and 'Amr al-Naqid narrated to us—Yahya said: Hushaym ibn Bashir informed us, from 'Abdullah ibn Abi Salih; and 'Amr said: Hushaym ibn Bashir narrated to us, 'Abdullah ibn Abi Salih informed us—from his father, from Abu Hurayrah, who said: The Messenger of Allah, peace and blessings be upon him, said: "Your oath is according to what your companion believes you upon." And 'Amr said: "Your companion believes you upon it."
