Anas b. Malik did not like that a person should pick out his white hair from his head or beard, and Messenger of Allah ﷺ did not dye, and there was some whiteness in his hair at his chin, on his temples and very little on his head.
أَنْ يَنْتِفَ الرَّجُلُ الشَّعْرَةَ الْبَيْضَاءَ مِنْ رَأْسِهِ وَلِحْيَتِهِ قَالَ وَلَمْ يَخْتَضِبْ رَسُولُ اللَّهِ ﷺ إِنَّمَا كَانَ الْبَيَاضُ فِي عَنْفَقَتِهِ وَفِي الصُّدْغَيْنِ وَفِي الرَّأْسِ نَبْذٌ
