[Machine] From the Messenger of Allah ﷺ that he used to say, "Do not sell the fruit until its ripeness is apparent," and he forbade the seller and the buyer from engaging in deceitful practices. The Messenger of Allah ﷺ also forbade selling the fruit of one's wall if it is dates, except by weight, and if it is grapes, except by raisins. And if it is a crop, it should be sold by a known weight. He forbade all of these practices.
عَنْ رَسُولِ اللهِ ﷺ أَنَّهُ كَانَ يَقُولُ لَا تَتَبَايَعُوا الثَّمَرَةَ حَتَّى يَبْدُوَ صَلَاحُهَا نَهَى الْبَائِعَ وَالْمُشْتَرِيَ وَنَهَى رَسُولُ اللهِ ﷺ عَنِ الْمُزَابَنَةِ أَنْ يَبِيعَ ثَمَرَةَ حَائِطِهِ إِنْ كَانَتْ نَخْلًا بِتَمْرٍ كَيْلًا وَإِنْ كَانَتْ كَرْمًا أَنْ يَبِيعَهُ بِزَبِيبٍ كَيْلًا وَإِنْ كَانَتْ زَرْعًا أَنْ يَبِيعَهُ بِكَيْلٍ مَعْلُومٍ نَهَى عَنْ ذَلِكَ كُلِّهِ
