Ash-Shama'il Al-Muhammadiyah, Book 5, Hadith 42 (English) ⓘ

Abu Rimtha Taymi R.A. says: "I went with my son to Rasulullah (Sallallahu alaihe wasallam). (Probably he had not see Rasulullah (Sallallahu alaihe wasallam) before). When I saw him I said to myself immediately, 'This is the true Messenger of Allah'. At that time Rasulullah (Sallallahu alaihe wasallam) was wearing two pieces of green clothing. (His lungi-sarong, waist-wrap and shawl were both green). On a few hairs there were signs of old age, but those hair were red".

حَدَّثَنَا عَلِيُّ بْنُ حُجْرٍ، قَالَ‏:‏ حَدَّثَنَا شُعَيْبُ بْنُ صَفْوَانَ، عَنْ عَبْدِ الْمَلِكِ بْنِ عُمَيْرٍ، عَنِ إِيَادِ بْنِ لَقِيطٍ الْعِجْلِيِّ، عَنْ أَبِي رِمْثَةَ التَّيْمِيِّ، تَيْمِ الرَّبَابِ، قَالَ‏:‏ أَتَيْتُ النَّبِيَّ صلى الله عليه وسلم، وَمَعِي ابْنٌ لِي، قَالَ‏:‏ فَأَرَيْتُهُ، فَقُلْتُ لَمَّا رَأَيْتُهُ‏:‏ هَذَا نَبِيُّ اللهِ صلى الله عليه وسلم وَعَلَيْهِ ثَوْبَانِ أَخْضَرَانِ، وَلَهُ شَعَرٌ قَدْ عَلاهُ الشَّيْبُ، وَشَيْبُهُ أَحْمَرُ‏.‏
