Sahih Muslim · Hadith 6223
The Book Pertaining to the Excellent Qualities of the Holy Prophet (may Peace be upon them) and His - كتاب الفضائل
حدثنا نصر بن علي الجهضمي، حدثنا أبي، حدثنا المثنى بن سعيد، عن قتادة، عن أنس بن مالك، قال يكره أن ينتف الرجل، الشعرة البيضاء من رأسه ولحيته - قال - ولم يختضب رسول الله صلى الله عليه وسلم إنما كان البياض في عنفقته وفي الصدغين وفي الرأس نبذ .
Anas b. Malik did not like that a person should pick out his white hair from his head or beard, and Allah's Messenger (may peace be upon him) did not dye, and there was some whiteness in his hair at his chin, on his temples and very little on his head. This hadith has been narrated on the authority of Muthanna through the same chain of transmitters.
