Qatadah (may Allah be pleased with him) reports:
"I asked Anas (may Allah be pleased with him), 'Did Messenger of Allah ﷺ dye his hair?'" He replied: "The hair of Messenger of Allah ﷺ did not reach such a stage where one would use a dye; however Messenger of Allah (Sallallahu alihe wasallam) did have a few white hair on his temples, on the other hand Abu Bakr (may Allah be pleased with him)dyed his hair with Hina and Katm."

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ: أَخْبَرَنَا أَبُو دَاوُدَ، قَالَ: أَخْبَرَنَا هَمَّامٌ، عَنْ قَتَادَةَ، قَالَ: قُلْتُ لأَنَسِ بْنِ مَالِكٍ: هَلْ خَضَبَ رَسُولُ اللهِ ﷺ؟ قَالَ: لَمْ يَبْلُغْ ذَلِكَ، إِنَّمَا كَانَ شَيْبًا فِي صُدْغَيْهِ وَلَكِنْ أَبُو بَكْرٍ، خَضَبَ بِالْحِنَّاءِ وَالْكَتَمِ.
