Musannaf Ibn Abi Shayba 13:1972

Abu Bakr narrated to us, he said: Waki’ narrated to us, from Hasan ibn Salih, from ‘Abd al-A’la, who said: A woman came to Shurayh and brought him a witness. He said: "Bring me another witness." She said: "You are my witness." So he made her swear an oath and ruled in her favor.
