Musannaf Ibn Abi Shayba 27:821

Abu Mu'awiyah narrated to us, from 'Asim, from Abu 'Uthman, who said: A man came to Hudhayfah and said: "I intend to go out to Basra." He said: "Do not go out to it." He said: "I have relatives there." He said: "Do not go out." He said: "I must go out." He said: "Then stay at its edge (adwatiha), and do not stay in its center (sarbiha)."
