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)?' " (Using translation from Bukhārī 2208)
نَهَى رَسُولُ اللهِ ﷺ عَنْ بَيْعِ الثَّمَرَةِ ثَمَرَةِ النَّخْلِ حَتَّى تَزْهُوَ قُلْنَا لِأَنَسٍ مَا زَهْوُهُ؟ قَالَ يَحْمَرُّ قَالَ أَرَأَيْتَ إِذَا مَنَعَ اللهُ الثَّمَرَةَ بِمَ تَسْتَحِلُّ مَالَ أَخِيكَ؟
