Humayd reported,

Anas was asked, "Did the Messenger of Allah ﷺ dye his hair?"He replied that he had seen only about seventeen or twenty grey hairs at the front of his beard, and he added that the Prophet was not disfigured by grey hair.Someone asked Anas, "Is grey hair disfiguring?"He answered, "All of you dislike it. But Abu Bakr dyed his hair with henna and katam, and Umar dyed his with henna."

حدثنا ابن أبي عدي

عن حميد قال

سئل أنس هل خضب رسول الله ﷺ قال إنه لم ير من الشيب إلا نحوا من سبع عشرة أو عشرين شعرة في مقدم لحيته وقال إنه لم يشن بالشيب فقيل لأنس أشين هو قال كلكم يكرهه ولكن خضب أبو بكر بالحناء والكتم وخضب عمر بالحناء
