Kharīz ibn ʿUthmān reported:
"I asked ʿAbd Allāh ibn Busr (may Allah be pleased with him), the Companion of the Prophet ﷺ: 'Did you see the Prophet ﷺ when he was in old age?' He replied: 'He had a few white hairs in the tuft of his ʿanfaqah [the hair between the lower lip and chin].'" Reference: Sahih al-Bukhari 3546
حَدَّثَنَا عِصَامُ بْنُ خَالِدٍ، حَدَّثَنَا حَرِيزُ بْنُ عُثْمَانَ: أَنَّهُ سَأَلَ عَبْدَ اللَّهِ بْنَ بُسْرٍ صَاحِبَ النَّبِيِّ صلى الله عليه وسلم قَالَ: «أَرَأَيْتَ النَّبِيَّ صلى الله عليه وسلم كَانَ شَيْخًا؟». قَالَ: «كَانَ فِي عَنْفَقَتِهِ شَعَرَاتٌ بِيضٌ».
