Abu’r-Rimtha at-Taimi (the servant of ar-Rabab) said: "I came to the Prophet (Allah bless him and give him peace) with a son of mine, who said: 'So I was shown him, and I said when I saw him: ‘This is Allah’s Prophet (Allah bless him and give him peace). He is wearing two green garments, and he has hair that is topped with grayness, and its grayness is reddish'.”
