Sunan Abi Dawud 23:13

Narrated Ibn Abi Rizmah:

I heard my father say: A man said to Shu'bah: Sufyan opposed you (i.e. narrated a tradition which differs from your version). He replied: You racked my mind. I have been told that Yahya b. Ma'in said: If anyone opposes Sufyan, the version of Sufyan will be acceptable.
