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).
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
[Machine] I asked Anas ibn Malik, "Did the Messenger of Allah ﷺ dye his hair?" He replied, "He did not dye it. There was only something on his temples. However, Abu Bakr dyed his hair with henna and katam."
سَأَلْتُ أَنَسَ بْنَ مَالِكٍ أَخَضَبَ رَسُولُ اللهِ ﷺ؟ قَالَ لَمْ يَبْلُغْ ذَلِكَ إِنَّمَا كَانَ شَيْءٌ فِي صُدْغَيْهِ وَلَكِنَّ أَبَا بَكْرٍ خَضَبَ بِالْحِنَّاءِ وَالْكَتَمِ
[Machine] Anas ibn Malik was asked, did the Messenger of Allah ﷺ dye his hair? He replied, no, his hair was not gray. It was then said, O Abu Hamzah, what is gray hair? He said, it is when all of you dislike it. Abu Bakr would dye his hair using henna and katam (a type of hair dye), and Umar would dye his hair using henna.
سُئِلَ أَنَسُ بْنُ مَالِكٍ هَلْ خَضَبَ رَسُولُ اللهِ ﷺ؟ قَالَ لَا لَمْ يَشِنْهُ الشَّيْبُ قَالَ فَقِيلَ يَا أَبَا حَمْزَةَ وَشَيْنٌ هُوَ؟ قَالَ يُقَالُ كُلُّكُمْ يَكْرَهُهُ وَخَضَبَ أَبُو بَكْرٍ بِالْحِنَّاءِ وَالْكَتَمِ وَخَضَبَ عُمَرُ بِالْحِنَّاءِ
" عن حميد قَالَ: سَألتُ أنَس بن مالك أخَضَبَ النَّبِىُّ ﷺ قَالَ: لَمْ يُصِبْهُ الشَّيْبُ، وَلَكِن خَضَبَ أَبُو بَكْر بالحِنَّاءِ والكَتَم (*) وَخَضب عُمَرُ بِالحِنَّاءِ ".
