Explanation

The Prophet (may Allah's peace and blessings be upon him) forbade some of the sales of crops because of the harm they incur on one or both sides of the transaction (buyer and seller). These sales include Mukhābarah, which is to lease out land in return for the produce of a specified part of the land; Muhāqalah, which is to sell wheat in the ear in return for husked wheat (wheat separated from the chaff); Muzābanah, which is to sell dates on palm trees in return for dates. He also forbade selling fruit until its condition becomes clear that it is free from blight and good for eating, but he made an exception for ‘Araya (date-palms), i.e. ripe dates after their value is estimated, in return for the same value of fruit.
