Chapter 32: Prohibition Of Selling Fruits Before They Have Ripened - كتاب التجارات
حَدَّثَنَا مُحَمَّدُ بْنُ رُمْحٍ، أَنْبَأَنَا اللَّيْثُ بْنُ سَعْدٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، عَنْ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ قَالَ " لاَ تَبِيعُوا الثَّمَرَةَ حَتَّى يَبْدُوَ صَلاَحُهَا " . نَهَى الْبَائِعَ وَالْمُشْتَرِيَ .
It was narrated from Ibn 'Umar that the Messenger of Allah (ﷺ) said:
"Do not sell fruits until they have ripened." And he forbade (both) the seller and the purchaser (to engage in such a transaction).
