Sahl b. Abu Hathma said that God’s Messenger forbade the sale of fruit for dried dates but gave licence regarding the ariya for its sale on the basis of a calculation of what the dates would be when dry, yet those who bought them could eat them when fresh.
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.)
Abu Huraira said God's Messenger gave licence regarding the sale of ‘araya for a computation of their amount when dry, provided they were less than five wasqs*, or amounted to five wasqs. Dawud b. al Husain was doubtful
Jabir said that God’s Messenger forbade mukhabara, muhaqala and muzabana. Muhaqala means that a man sells a sown field for a hundred faraqs ( 3 sa’s) of wheat; muzabana that he sells the dates on the palm-trees for a hundred faraqs and mukharaba is renting land for a third and a quarter of the produce.
