Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) says that the Messenger of Allah (peace and blessings be upon him) "forbade muhaqalah, muzabanah, mukhabarah and mu'awamah," and the other (narrator) said: "He also forbade the sale of years and thunya, and he granted a concession for 'araya."
