Hadith 43:135
Anas b. Malik did not like that a person should pick out his white hair from his head or beard, and Allah's Messenger (ﷺ) did not dye, and there was some whiteness in his hair at his chin, on his temples and very little on his head.
حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ الْجَهْضَمِيُّ، حَدَّثَنَا أَبِي، حَدَّثَنَا الْمُثَنَّى بْنُ سَعِيدٍ، عَنْ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ يُكْرَهُ أَنْ يَنْتِفَ الرَّجُلُ، الشَّعْرَةَ الْبَيْضَاءَ مِنْ رَأْسِهِ وَلِحْيَتِهِ - قَالَ - وَلَمْ يَخْتَضِبْ رَسُولُ اللَّهِ صلى الله عليه وسلم إِنَّمَا كَانَ الْبَيَاضُ فِي عَنْفَقَتِهِ وَفِي الصُّدْغَيْنِ وَفِي الرَّأْسِ نَبْذٌ
