حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ مُسْلِمٍ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ دِينَارٍ، قَالَ سَمِعْتُ ابْنَ عُمَرَ ـ رضى الله عنهما ـ قَالَ كَانَ رَجُلٌ يُخْدَعُ فِي الْبَيْعِ فَقَالَ لَهُ النَّبِيُّ صلى الله عليه وسلم " إِذَا بَايَعْتَ فَقُلْ لاَ خِلاَبَةَ ". فَكَانَ يَقُولُهُ.
