حَدَّثَنِي ابْنُ بُكَيْرٍ، قَالَ حَدَّثَنِي اللَّيْثُ، عَنْ خَالِدٍ، عَنْ سَعِيدِ بْنِ أَبِي هِلاَلٍ، عَنْ رَبِيعَةَ بْنِ أَبِي عَبْدِ الرَّحْمَنِ، قَالَ سَمِعْتُ أَنَسَ بْنَ مَالِكٍ، يَصِفُ النَّبِيَّ صلى الله عليه وسلم قَالَ كَانَ رَبْعَةً مِنَ الْقَوْمِ، لَيْسَ بِالطَّوِيلِ وَلاَ بِالْقَصِيرِ، أَزْهَرَ اللَّوْنِ لَيْسَ بِأَبْيَضَ أَمْهَقَ وَلاَ آدَمَ، لَيْسَ بِجَعْدٍ قَطَطٍ وَلاَ سَبْطٍ رَجِلٍ، أُنْزِلَ عَلَيْهِ وَهْوَ ابْنُ أَرْبَعِينَ، فَلَبِثَ بِمَكَّةَ عَشْرَ سِنِينَ يُنْزَلُ عَلَيْهِ وَبِالْمَدِينَةِ عَشْرَ سِنِينَ، وَلَيْسَ فِي رَأْسِهِ وَلِحْيَتِهِ عِشْرُونَ شَعَرَةً بَيْضَاءَ‏.‏ قَالَ رَبِيعَةُ فَرَأَيْتُ شَعَرًا مِنْ شَعَرِهِ، فَإِذَا هُوَ أَحْمَرُ فَسَأَلْتُ فَقِيلَ احْمَرَّ مِنَ الطِّيبِ‏.‏

I heard Anas bin Malik describing the Prophet (ﷺ) saying, "He was of medium height amongst the people, neither tall nor short; he had a rosy color, neither absolutely white nor deep brown; his hair was neither completely curly nor quite lank. Divine Inspiration was revealed to him when he was forty years old. He stayed ten years in Mecca receiving the Divine Inspiration, and stayed in Medina for ten more years. When he expired, he had scarcely twenty white hairs in his head and beard." Rabi`a said, "I saw some of his hairs and it was red. When I asked about that, I was told that it turned red because of scent. "
