Abu Dawud said: I heard Ahmad b. Hanbal say: I have corrupted this tradition for us. He was asked: Do you think that it is correct that this tradition has been corrupted? Has any person other than Ibn Abi Uwais transmitted it ? He replied: Ayyub was similar to him in respect of reliability, and Ayyub transmitted it.
