حَدَّثَنَا أَحْمَدُ بْنُ سَعِيدٍ أَبُو عَبْدِ اللَّهِ، حَدَّثَنَا إِسْحَاقُ بْنُ مَنْصُورٍ، حَدَّثَنَا إِبْرَاهِيمُ بْنُ يُوسُفَ، عَنْ أَبِيهِ، عَنْ أَبِي إِسْحَاقَ، قَالَ سَمِعْتُ الْبَرَاءَ، يَقُولُ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم أَحْسَنَ النَّاسِ وَجْهًا وَأَحْسَنَهُ خَلْقًا، لَيْسَ بِالطَّوِيلِ الْبَائِنِ وَلاَ بِالْقَصِيرِ.
