Narrated Anas bin Malik (RA):
The Prophet (ﷺ) forbade the sale of fruits till they become colorful. He was asked what that meant, he replied, "Till they become reddish and yellowish." [Agreed upon and the wording is al-Bukhari's].
وَعَنْ أَنَسِ بْنِ مَالِكٍ ‏- رضى الله عنه ‏- { أَنَّ اَلنَّبِيَّ ‏- صلى الله عليه وسلم ‏-نَهَى عَنْ بَيْعِ اَلثِّمَارِ حَتَّى تُزْهَى.‏ قِيلَ: وَمَا زَهْوُهَا? قَالَ: " تَحْمَارُّ وَتَصْفَارُّ } مُتَّفَقٌ عَلَيْهِ , وَاللَّفْظُ لِلْبُخَارِيِّ 1‏ .‏
