Muhammad ibn Abdullah ibn Numayr and Muhammad ibn Tarif al-Bajali narrated to me — and the wording is that of Ibn Tarif — they said: Muhammad ibn Fudayl narrated to us, from al-A'mash, from Abd al-Aziz ibn Rufay', from Tamim al-Ta'i, from Adi, who said: The Messenger of Allah, peace and blessings be upon him, said: "When one of you swears an oath and then sees something better than it, let him expiate for his oath and do that which is better."
