وَعَن أبي رِمْثةَ التيميِّ
قَالَ: أَتَيْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَعَلَيْهِ ثَوْبَانِ أَخْضَرَانِ وَلَهُ شَعَرٌ قَدْ عَلَاهُ الشَّيْبُ وَشَيْبُهُ أَحْمَرُ وَفِي رِوَايَةٍ لِأَبِي دَاوُدَ: وَهُوَ ذُو وَفْرَةٍ وَبِهَا رَدْعٌ من حناء
When I came to the Prophet (sallallahu alayhi wa sallam) he was wearing two green garments, his hair was turning grey, but the grey was dyed red.
