Volume 3, Book 34, Number 410:
Narrated Humaid:
Anas said, “The Prophet 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 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)?’ “
