Anas b. Malik was asked whether Messenger of Allah ﷺ dyed his hair. He said: He had not become old enough to have white hair. Ibn Idris said that he had a few white hair. Abu Bakr and Umar, however, dyed hair with hina' (henna).
سُئِلَ أَنَسُ بْنُ مَالِكٍ هَلْ خَضَبَ رَسُولُ اللَّهِ ﷺ قَالَ إِنَّهُ لَمْ يَكُنْ رَأَى مِنَ الشَّيْبِ إِلاَّ قَالَ ابْنُ إِدْرِيسَ كَأَنَّهُ يُقَلِّلُهُ وَقَدْ خَضَبَ أَبُو بَكْرٍ وَعُمَرُ بِالْحِنَّاءِ وَالْكَتَمِ
[Machine] I asked Anas ibn Malik, "Did the Messenger of Allah ﷺ dye his hair?" He said, "He never had a lot of gray hair to begin with, only a little. Abu Bakr and Umar used to dye their hair with henna and katam."
سَأَلْتُ أَنَسَ بْنَ مَالِكٍ هَلْ خَضَبَ رَسُولُ اللهِ ﷺ؟ قَالَ لَمْ يَكُنْ رَأَى يَعْنِي مِنَ الشَّيْبِ إِلَّا يَسِيرًا وَقَدْ خَضَبَ أَبُو بَكْرٍ وَعُمَرُ أَحْسِبُ 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
