Sahih al-Bukhari, Hadith 3762 ⓘ
Narrated `Abdur-Rahman bin Yazid: We asked Hudhaifa to tell us of a person resembling (to some extent) the Prophet in good appearance and straight forward behavior so that we may learn from him (good manners and acceptable conduct). Hudhaifa replied, "I do not know anybody resembling the Prophet (to some extent) in appearance and conduct more than Ibn Um `Abd.
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.
