The questioner : The questioner says: O honorable Shaykh, what is the ruling on changing the gray hair in the beard, mustache, and head? If it is a recommended practice, why do we see many scholars not doing it?

The Shaykh : Changing gray hair to a color other than black is a recommended practice (sunnah) that the Prophet (peace and blessings be upon him) commanded, saying: However, many scholars do not do this because of the difficulty of monitoring it, as a person must constantly check the hair, otherwise its original color will become apparent and clear.

The Mufti of this land, Shaykh Muhammad ibn Ibrahim (may Allah have mercy on him), also did not dye his gray hair, nor did his brothers, nor many of the scholars we have seen.

As for black, the Prophet (peace and blessings be upon him) said:
