‘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.
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
Narrated Anas said that God’s Messenger forbade the sale of fruits till tuzhiya. He was asked what that meant and said it meant till they became red, adding, “Tell me:
when God keeps back the fruit, why should any of you take his brother’s property?”
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.
