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
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.
‘Abdallah b. ‘Umar said that God's Messenger forbade the sale of fruits till they were clearly in good condition, forbidding it both to the seller and to the buyer. A version by Muslim says he forbade selling palm-trees (i.e. their fruit) till the dates began to ripen, and ears of corn till they were white and were safe from blight.
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.)
