And it was narrated to us by Isḥāq ibn Ibrāhīm and ʿAbd ibn Ḥumayd, both saying: narrated to us ʿAbd al-Razzāq, informing us Maʿmar, from Ibn Ṭāwūs, from his father, from Ibn ʿAbbās, who said: The Messenger of Allah, peace and blessings be upon him, forbade meeting the caravans [to intercept them before reaching the market] and forbade that a resident sell on behalf of a Bedouin. He said: So I said to Ibn ʿAbbās, "What does his saying 'a resident sell on behalf of a Bedouin' mean?" He said, "He should not be a broker for him."
