The Prophet (ﷺ) forbade the sales called Al-Mukhabara, Al-Muhaqala and Al-Muzabana and the selling of fruits till they are free from blights. He forbade the selling of the fruits except for money, except the 'Araya.
Sahih al-Bukhari Book 42, Hadith 29
← Previous Hadith The Prophet (ﷺ) permitted selling the dates of the 'Araya for ready dates by estimating the amount of the former (as they are still on the trees).

Sahih al-Bukhari Book 42, Hadith 28 Next Hadith → The Prophet (ﷺ) allowed the sale of the dates of the 'Araya for ready dates by estimating the former which should be estimated as less than five Awsuq or five Awsuq. (Dawud, the sub-narrator is not sure as to the right amount.)
