Musannaf Ibn Abi Shayba 13:934

Abu Bakr narrated to us, he said: Ibn 'Uyaynah narrated to us, from Abu al-Zubayr, he heard Jabir saying: The Messenger of Allah (may Allah bless him and grant him peace) said: "A resident should not sell for a bedouin. Leave the people, so that Allah may provide for some of them through others."
