Ibn Sirin reported
Anas b. Malik 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 and Umar, however, dyed hair with hina' (henna).
Ibn Sirin reported
I asked Anas b. Malik 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 dye his hair? He said: Yes, with hina' (henna).
Muhammad b. Sirin reported
I asked Anas b. Malik whether Allah's Messenger (ﷺ) dyed his hair. He said: He had but little white hair.
Thabit reported that Anas b. Malik 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 b. Malik 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.
This hadith has been narrated on the authority of Muthanna through the same chain of transmitters.
Anas (b. Malik) was asked about the old age of Allah's Apostle (ﷺ). He said
Allah did not blemish him with white hair.
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).
Abu Juhaifa reported
I saw Allah's Messenger (ﷺ) that he had white complexion and had some white hair, and Hasan b. 'Ali resembled him.
This hadith has been transmitted on the authority of Abu Juhaifa with a slight variation of wording.
Jabir b. Samura 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.
Jabir b. Samura reported that there had appeared some whiteness on the front part of the head and beard of Allah's Messenger (ﷺ). When he applied oil, it did not become visible, but when he did not (apply) oil, it became apparent. And he had a thick beard. A person said
His face was as (bright) as the sword. Thereupon he (Jabir) said: No, it was round and like the sun and the moon. And I saw the seal near his shoulder of the size of a pigeon's egg and its color was the same as that of his body.
