Ibn Sirin reported: Anas bin Malik (RA) was asked whether Allah's Messenger (ﷺ) dyed his hair. He said: He had not become old enough to have white hair. Ibn Idris said that he had a few white hair. Abu Bakr (RA) and Umar, however, dyed hair with hina' (henna).
Ibn Sirin reported: I asked Anas bin Malik (RA) whether Allah's Messenger (ﷺ) dyed his hair. He said: He had not reached the stage when (he needed) dyeing (of his white hair). He had a few white hair in his beard. I said to him: Did Abu Bakr (RA) dye his hair? He said: Yes, with hina' (henna).
Thabit reported that Anas bin Malik (RA) was asked about the dyeing (of the hair of) Allah's Apostle (ﷺ) . Thereupon he said.: (They were so few) that if I so liked I could count their number in his head, and he further said: (That is) he did not dye. Abu Bakr, however, dyed them and so did 'Umar dye them with pure henna.
Anas bin Malik (RA) did not like that a person should pick out his white hair from his head or beard, and Allah's Messenger (ﷺ) did not dye, and there was some whiteness in his hair at his chin, on his temples and very little on his head.
Abu Juhaifa reported: I saw Allah's Messenger (ﷺ) having some whiteness (in hair) at this place, and Zuhair placed one of his fingers at his chin. Juhaifa was asked how old he had been at that time. He said: I made arrows and put feathers to them (i. e. I had passed my childhood).
Jabir bin ahadeeth was asked about the old age of Allah's Apostle (ﷺ) . He said: When he oiled his head nothing was seen (as a mark of old age) and when he did not apply oil something (of the old age) became visible.
