حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي إِسْحَاقَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ يَزِيدَ،، قَالَ سَأَلْنَا حُذَيْفَةَ عَنْ رَجُلٍ، قَرِيبِ السَّمْتِ وَالْهَدْىِ مِنَ النَّبِيِّ صلى الله عليه وسلم حَتَّى نَأْخُذَ عَنْهُ فَقَالَ مَا أَعْرِفُ أَحَدًا أَقْرَبَ سَمْتًا وَهَدْيًا وَدَلاًّ بِالنَّبِيِّ صلى الله عليه وسلم مِنِ ابْنِ أُمِّ عَبْدٍ.
