Sahih al-Bukhari, Book 34, Hadith 145 (In-Book) ⓘ

p> Narrated Anas bin Malik: Allah's Messenger forbade the sale of fruits till they are almost ripe. He was asked what is meant by 'are almost ripe.' He replied, "Till they become red." Allah's Messenger further said, "If Allah spoiled the fruits, what right would one have to take the money of one's brother (i.e. other people)?"

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ حُمَيْدٍ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنْ بَيْعِ الثِّمَارِ حَتَّى تُزْهِيَ‏.‏ فَقِيلَ لَهُ وَمَا تُزْهِي قَالَ حَتَّى تَحْمَرَّ‏.‏ فَقَالَ ‏ "‏ أَرَأَيْتَ إِذَا مَنَعَ اللَّهُ الثَّمَرَةَ، بِمَ يَأْخُذُ أَحَدُكُمْ مَالَ أَخِيهِ ‏" ‏‏.‏
