Sunan Abi Dawud 3291
Oaths and Vows (Kitab Al-Aiman Wa Al-Nudhur)
The View That Atonement Is Necessary If A Man Vows To Disobey Allah
The tradition mentioned above has also been transmitted by al-Zuhri through a different chain of narrators to the same effect. Abu Dawud said: I heard Ahmad b. Shabbuyah say: Ibn al-Mubarak said about this tradition that Abu Salamah had transmitted it. This indicates that al-Zuhri did not hear it from Abu Salamah. Ahmad b. Muhammad said: This is verified by what Ayyub b. Sulaiman narrated to us. 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.
