حَدَّثَنَا أَبُو بَكْرٍ، حَدَّثَنَا شَبَابَةُ، حَدَّثَنَا شُعْبَةُ، عَنْ خَالِدٍ الْحَذَّاءِ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي بَكْرَةَ، عَنْ أَبِيهِ، قَالَ مَدَحَ رَجُلٌ رَجُلاً عِنْدَ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ فَقَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏"‏ وَيْحَكَ قَطَعْتَ عُنُقَ صَاحِبِكَ ‏"‏ ‏.‏ مِرَارًا ثُمَّ قَالَ ‏"‏ إِنْ كَانَ أَحَدُكُمْ مَادِحًا أَخَاهُ فَلْيَقُلْ أَحْسِبُهُ وَلاَ أُزَكِّي عَلَى اللَّهِ أَحَدًا ‏"‏ ‏.‏
