حَدَّثَنَا مُحَمَّدُ بْنُ بَكَّارِ بْنِ الرَّيَّانِ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ زَكَرِيَّاءَ، عَنْ عَاصِمٍ الأَحْوَلِ، عَنِ ابْنِ سِيرِينَ، قَالَ سَأَلْتُ أَنَسَ بْنَ مَالِكٍ هَلْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم خَضَبَ فَقَالَ لَمْ يَبْلُغِ الْخِضَابَ كَانَ فِي لِحْيَتِهِ شَعَرَاتٌ بِيضٌ ‏.‏ قَالَ قُلْتُ لَهُ أَكَانَ أَبُو بَكْرٍ يَخْضِبُ قَالَ فَقَالَ نَعَمْ بِالْحِنَّاءِ وَالْكَتَمِ ‏.‏
