Anas said, "The Prophet (ﷺ) forbade the selling of dates till they were almost ripe." We asked Anas, "What does 'almost ripe' mean?" He replied, "They get red and yellow. The Prophet (ﷺ) added, 'If Allah destroyed the fruits present on the trees, what right would the seller have to take the money of his brother (somebody else)?' "

← Previous Hadith Allah's Messenger (ﷺ) forbade Muhaqala, Mukhadara, Mulamasa, Munabadha and Muzabana. (See glossary and previous Hadiths for the meanings of these terms.)

Sahih al-Bukhari Book 34, Hadith 153 Next Hadith → I was with the Prophet (ﷺ) while he was eating fresh dates. He said, "From the trees there is a tree which resembles a faithful believer." I wanted to say that it was the date palm, but I was the youngest among them (so I kept quiet). He added, "It is the date palm."
