He said that God’s Messenger forbade muhaqala, muzabana, mukhabara, mu'awama (Selling a year’s harvest before the crop has grown, or selling the fruit on one’s palm-trees two or three years ahead.) and thunya (An exception the amount of which is not accurately known.), but gave licence for ‘araya (Plural of ‘ariya. A palm-tree assigned by its owner to another who is in need, for him to eat its fruit for a year. It is said that a poor man who had no money to buy fresh dates might buy the fruit on a palm-tree for dry dates.) Muslim transmitted it.
