[Machine] Anas was asked if the Prophet ﷺ used to dye his hair. He replied, "The grey hairs of the Messenger of Allah ﷺ did not reach to the point where he would dye them. If I wanted to count the white hairs in his beard, I could, but Abu Bakr used to dye his hair with henna and katam, and Umar used to dye his hair with henna."
أَنَّ أَنَسًا سُئِلَ خَضَبَ النَّبِيُّ ﷺ؟ قَالَ لَمْ يَبْلُغْ شَيْبُ رَسُولِ اللهِ ﷺ مَا كَانَ يَخْضِبُ وَلَوْ شِئْتُ أَنْ أَعُدَّ شَمَطَاتٍ كُنَّ فِيلِحْيَتِهِ لَفَعَلْتُ وَلَكِنَّ أَبَا بَكْرٍ كَانَ يَخْضِبُ بِالْحِنَّاءِ وَالْكَتَمِ وَكَانَ عُمَرُ يَخْضِبُ بِالْحِنَّاءِ
