Ubayd Allah ibn Umar al-Qawariri and Muhammad ibn Ubayd al-Ghubari narrated to us — and the wording is that of Ubayd Allah — they said: Hammad ibn Zayd narrated to us, from Ayyub, from Abu al-Zubayr and Sa'id ibn Mina', from Jabir ibn Abd Allah, who said: The Messenger of Allah, peace and blessings be upon him, forbade al-muhaqalah, al-muzabanah, al-mu'awamah, and al-mukhabarah — one of the two said: "selling for years," which is al-mu'awamah — and he forbade al-thunyah, but he granted a concession regarding al-'araya.
