حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَابْنُ، نُمَيْرٍ وَعَمْرٌو النَّاقِدُ جَمِيعًا عَنِ ابْنِ إِدْرِيسَ، - قَالَ عَمْرٌو حَدَّثَنَا عَبْدُ اللَّهِ بْنُ إِدْرِيسَ الأَوْدِيُّ، - عَنْ هِشَامٍ، عَنِ ابْنِ سِيرِينَ، قَالَ سُئِلَ أَنَسُ بْنُ مَالِكٍ هَلْ خَضَبَ رَسُولُ اللَّهِ صلى الله عليه وسلم قَالَ إِنَّهُ لَمْ يَكُنْ رَأَى مِنَ الشَّيْبِ إِلاَّ - قَالَ ابْنُ إِدْرِيسَ كَأَنَّهُ يُقَلِّلُهُ - وَقَدْ خَضَبَ أَبُو بَكْرٍ وَعُمَرُ بِالْحِنَّاءِ وَالْكَتَمِ ‏.‏

Ibn Sirin reported

I asked Anas b. Malik whether Allah's Messenger (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).
