One who does not dye his hair
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا خَالِدُ بْنُ الْحَارِثِ، وَابْنُ أَبِي عَدِيٍّ، عَنْ حُمَيْدٍ، قَالَ سُئِلَ أَنَسُ بْنُ مَالِكٍ أَخَضَبَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ قَالَ إِنَّهُ لَمْ يَرَ مِنَ الشَّيْبِ إِلاَّ نَحْوَ سَبْعَةَ عَشَرَ أَوْ عِشْرِينَ شَعَرَةً فِي مُقَدَّمِ لِحْيَتِهِ .
It was narrated that Humaid said: “Anas bin Malik was asked: ‘Did the Messenger of Allah (ﷺ) dye his hair?’ He said: ‘He did not have any white hair apart from approximately seventeen or twenty hairs at the front of his beard.’”
