Ibn Sirin reported: I asked Anas b. Malik whether Messenger of Allah 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).

حَدَّثَنَا مُحَمَّدُ بْنُ بَكَّارِ بْنِ الرَّيَّانِ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ زَكَرِيَّاءَ، عَنْ عَاصِمٍ الأَحْوَلِ،
عَنِ ابْنِ سِيرِينَ، قَالَ سَأَلْتُ أَنَسَ بْنَ مَالِكٍ هَلْ كَانَ رَسُولُ اللَّهِ ﷺ خَضَبَ
فَقَالَ لَمْ يَبْلُغِ الْخِضَابَ كَانَ فِي لِحْيَتِهِ شَعَرَاتٌ بِيضٌ . قَالَ قُلْتُ لَهُ أَكَانَ أَبُو بَكْرٍ يَخْضِبُ
قَالَ فَقَالَ نَعَمْ بِالْحِنَّاءِ وَالْكَتَمِ .
