Anas said that God’s Messenger forbade the sale of fruits till <i>tuzhiya</i>. He was asked what that meant and said it meant till they became red, adding, “Tell me:

when God keeps back the fruit, why should any of you take his brother’s property?” (Bukhari and Muslim.)

وَعَنْ أَنَسٍ قَالَ: نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَن بيع الثِّمَارِ حَتَّى تَزْهَى قِيلَ: وَمَا تَزْهَى؟ قَالَ: حَتَّى تخمر " وَقَالَ: «أَرَأَيْتَ إِذَا مَنَعَ اللَّهُ الثَّمَرَةَ بِمَ يَأْخُذ أحدكُم مَال أَخِيه؟»
