حَدَّثَنَا عَلِيُّ بْنُ حُجْرٍ قَالَ حَدَّثَنَا إِسْمَعِيلُ قَالَ حَدَّثَنَا أَبُو سُهَيْلٍ نَافِعُ بْنُ مَالِكِ بْنِ أَبِي عَامِرٍ عَنْ أَبِيهِ عَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ آيَةُ النِّفَاقِ ثَلَاثٌ إِذَا حَدَّثَ كَذَبَ وَإِذَا وَعَدَ أَخْلَفَ وَإِذَا اؤْتُمِنَ خَانَ
