The prohibition of selling fresh dates in exchange for dry dates except in the case of 'Araya Sahih Muslim 1542 g
Translation
Abdullah (b. Umar) (Allah be pleased with them) reported Allah's Messenger (ﷺ) having forbidden Mazabana, and it implies that one should sell the fresh fruits of his orchard (for dry fruits) or, if it is fresh dates, for dry dates with a measure, or if it is grapes for raisins or if it is corn in the field for dry corn with a measure He (the Holy Prophet) in fact forbade all such transactions. Qutaiba has narrated it with a slight variation of words.
