Sahih Muslim – Hadith No : 6223

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.
