أَخْبَرَنَا يُوسُفُ بْنُ حَمَّادٍ، قَالَ حَدَّثَنَا عَبْدُ الأَعْلَى، عَنْ سَعِيدٍ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، أَنَّ رَجُلاً، كَانَ فِي عُقْدَتِهِ ضَعْفٌ كَانَ يُبَايِعُ وَأَنَّ أَهْلَهُ أَتَوُا النَّبِيَّ صلى الله عليه وسلم فَقَالُوا يَا نَبِيَّ اللَّهِ احْجُرْ عَلَيْهِ . فَدَعَاهُ نَبِيُّ اللَّهِ صلى الله عليه وسلم فَنَهَاهُ فَقَالَ يَا نَبِيَّ اللَّهِ إِنِّي لاَ أَصْبِرُ عَنِ الْبَيْعِ . قَالَ " إِذَا بِعْتَ فَقُلْ لاَ خِلاَبَةَ " .
Anas reported that a man with limited understanding used to buy and sell. His family came to the Prophet and said: Prophet of Allah, place a restriction on him. The Prophet called him and told him not to trade. The man said: Prophet of Allah, I cannot keep away from buying and selling. He said: Whenever you make a sale, say: There is no deception.
