“I came to the Prophet (ﷺ) with a son of mine, so he said; ‘Is this your son?’ I said: ‘Yes, I acknowledge him!’ He said: ‘He must not harm you, and you must not harm him!’ I also noticed that the grayness of his hair was reddish.”
“Did Allah’s Messenger (ﷺ) dye [his hair]?” He said: “Yes!”
حَدَّثَنَا سُفْيَانُ بْنُ وَكِيعٍ، قَالَ: حَدَّثَنَا أَبِي، عَنْ شَرِيكٍ، عَنْ عُثْمَانَ بْنِ مَوْهَبٍ، قَالَ: سُئِلَ أَبُو هُرَيْرَةَ: هَلْ خَضَبَ رَسُولُ اللهِ صلى الله عليه وسلم؟ قَالَ: نَعَمْ.

Al-Jahdama, the wife of Bishr ibn al- Khasasiyya, said:
"I saw Allah’s Messenger (ﷺ) come out of his house shaking his head, for he had performed the major ritual ablution, and on his head there was some trace of henna." (Or he said: saffron. The Shaikh doubted this.)
