Sunan Abi Dawud 2208

Ali b. Yazid b. Rukanah reported on the authority of his father from his grandfather that he (Rukanah) divorced his wife absolutely; so he came to the Messenger of Allah (ﷺ). He asked (him):What did you intend? He said: A single utterance of divorce. He said: Do you swear by Allah? He replied: I swear by Allah. He said: It stands as you intended. Abu Dawud said: This tradition is sounder than that of Ibn Juraij that Rukanah divorced his wife by three pronouncements, for they are the members of his family and they are more aware for him. The tradition of Ibn Juraij has been narrated by some children of Abu Rafi' from 'Ikrimah on the authority of Ibn 'Abbas
