Arabic

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنْ فُضَيْلِ بْنِ غَزْوَانَ، عَنِ ابْنِ أَبِي نُعْمٍ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ سَمِعْتُ أَبَا الْقَاسِمِ، صلى الله عليه وسلم يَقُولُ ‏ "‏ مَنْ قَذَفَ مَمْلُوكَهُ وَهْوَ بَرِيءٌ مِمَّا قَالَ، جُلِدَ يَوْمَ الْقِيَامَةِ، إِلاَّ أَنْ يَكُونَ كَمَا قَالَ ‏"‏‏.‏
