Hadith 709

Narrated Ibn 'Umar (RA): Allah's Messenger (ﷺ) forbade al-Muzabanah, which means that a man sells the fruit of his garden, if it consists of palm-trees (fresh dates), for dried dates by measure; or if it consists of grapes (on the vines), for raisins by measure; or if it is unpicked crops, he sells it for a measured amount of picked crops. He forbade all that. [Agreed upon].
