Musannaf Ibn Abi Shayba 28:1181

Ibn Mahdi narrated to us, from Sufyan, from Zubayd, from Sa'd ibn 'Ubaydah, from Abu 'Abd al-Rahman al-Sulami, from 'Ali, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "There is no obedience to any human being in disobedience to Allah."
