حَدَّثَنِي أَبُو الرَّبِيعِ الْعَتَكِيُّ، حَدَّثَنَا حَمَّادٌ، حَدَّثَنَا ثَابِتٌ، قَالَ سُئِلَ أَنَسُ بْنُ مَالِكٍ عَنْ خِضَابِ النَّبِيِّ، صلى الله عليه وسلم فَقَالَ لَوْ شِئْتُ أَنْ أَعُدَّ شَمَطَاتٍ كُنَّ فِي رَأْسِهِ فَعَلْتُ . وَقَالَ لَمْ يَخْتَضِبْ وَقَدِ اخْتَضَبَ أَبُو بَكْرٍ بِالْحِنَّاءِ وَالْكَتَمِ وَاخْتَضَبَ عُمَرُ بِالْحِنَّاءِ بَحْتًا .
English Translation
Thabit reported that Anas b. Malik was asked about the dyeing (of the hair of) Allah's Apostle (ﷺ). Thereupon he said.:(They were so few) that if I so liked I could count their number in his head, and he further said: (That is) he did not dye. Abu Bakr, however, dyed them and so did 'Umar dye them with pure henna
