حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ: حَدَّثَنَا وَهْبُ بْنُ جَرِيرِ بْنِ حَازِمٍ، قَالَ: حَدَّثَنِي أَبِي، عَنْ قَتَادَةَ، قَالَ: قُلْتُ لأَنَسٍ: كَيْفَ كَانَ شَعَرُ رَسُولِ اللهِ صلى الله عليه وسلم؟ قَالَ: لَمْ يَكُنْ بِالْجَعْدِ، وَلا بِالسَّبْطِ، كَانَ يَبْلُغُ شَعَرُهُ شَحْمَةَ أُذُنَيْهِ.
