Sahih al-Bukhari, Volume 3, Book 34, Hadith 403 (USC-MSA) ⓘ
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 " .

Narrated Ibn Shihab: If somebody bought fruits before their benefit is evident and then the fruits were spoiled with blights, the loss would be suffered by the owner (not the buyer). Narrated Salim bin 'Abdullah from Ibn Umar: Allah's Messenger said, "Do not sell or buy fruits before their benefit was evident and do not sell fresh fruits (dates) for dried dates."
قَالَ اللَّيْثُ حَدَّثَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، قَالَ لَوْ أَنَّ رَجُلاً، ابْتَاعَ ثَمَرًا قَبْلَ أَنْ يَبْدُوَ صَلاَحُهُ، ثُمَّ أَصَابَتْهُ عَاهَةٌ، كَانَ مَا أَصَابَهُ عَلَى رَبِّهِ، أَخْبَرَنِي سَالِمُ بْنُ عَبْدِ اللَّهِ عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ تَتَبَايَعُوا الثَّمَرَ حَتَّى يَبْدُوَ صَلاَحُهَا، وَلاَ تَبِيعُوا الثَّمَرَ بِالتَّمْرِ " .
