Allah's Messenger (ﷺ) forbade Muzabana; and Muzabana means the selling of fresh dates (on the trees) for dried dates by measure and also the selling of fresh grapes for dried grapes by measure.
Sahih al-Bukhari Book 34, Hadith 132
← Previous Hadith Allah's Messenger (ﷺ) said, "Do not sell fruits of dates until they become free from all the dangers of being spoilt or blighted; and do not sell fresh dates for dry dates." Narrated Salim and `Abdullah from Zaid bin Habit' "Later on Allah's Messenger (ﷺ) permitted the selling of ripe fruits on trees for fresh dates or dried dates in Bai'-al-'Araya, and did not allow it for any other kind of sale."

Sahih al-Bukhari Book 34, Hadith 131 Next Hadith → Allah's Messenger (ﷺ) forbade Muzabana and Muhaqala; and Muzabana means the selling of ripe dates for dates still on the trees.
