حَدَّثَنَا مُوسَی بْنُ إِسْمَاعِيلَ حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ مُسْلِمٍ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ دِينَارٍ قَالَ سَمِعْتُ ابْنَ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا قَالَ کَانَ رَجُلٌ يُخْدَعُ فِي الْبَيْعِ فَقَالَ لَهُ النَّبِيُّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا بَايَعْتَ فَقُلْ لَا خِلَابَةَ فَکَانَ يَقُولُهُ
