Narrated 'Abdullah bin 'Umar:
A man mentioned to the Prophet that he had always been cheated in bargains. The Prophet ﷺ said, "Whenever you do bargain, say, 'No cheating.'"
حَدَّثَنَا إِسْمَاعِيلُ، حَدَّثَنَا مَالِكٌ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ ـ رضى الله عنهما ـ أَنَّ رَجُلاً، ذَكَرَ لِلنَّبِيِّ ﷺ أَنَّهُ يُخْدَعُ فِي الْبُيُوعِ فَقَالَ
" إِذَا بَايَعْتَ فَقُلْ لاَ خِلاَبَةَ ".
