‘I said to Anas ibn Malik:“Did Allah’s Messenger (Allah bless him and give him peace) dye his hair?” He replied: ‘He did not get to that, for he was grayed only in the hair covering his temples, but Abu Bakr (may Allah the Exalted be well pleased with him) dyed his hair with henna and a herbal mixture called katam.”

"On the head of Allah’s Messenger (Allah bless him and give him peace) and his beard, I counted only fourteen white hairs.”

"When he oiled his head, no grayness was visible, and when he did not apply oil, some was visible.”

"The hoariness of Allah’s Messenger (Allah bless him and give him peace) was merely about twenty white hairs."

Abu Bakr said: “O Messenger of Allah, you have grayed!” He said: 'I have been made gray-haired by Hud (Al-Qur'an; 11)), the calamity (Al-Qur'an; 56)), the winds sent forth (Al-Qur'an; 77)). what will they question one another about?’ (Al-Qur'an; 74)). and ‘when the sun is overthrown’ (Al-Qur'an; 81)'."

"O Messenger of Allah we notice that you have turned gray!’ He said: ‘The [Sura of] Hud and its sisters have caused me to turn gray!’”

"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'.”

“Was there any grayness of the head of Allah’s Messenger (Allah bless him and give him peace)?" He replied: "There was no grayness on the head of Allah’s Messenger (Allah bless him and give him peace), except some hairs in the part of his hair when he applied oil and the oil made them visible.”
