Is it permissible to dye the beard black?

It is not permissible for a man to dye his beard black, due to the prohibition of the Prophet, peace and blessings be upon him, concerning that. It is desirable to change grey hair with a color other than black. It is legislated to dye hair with henna and anything that gives it a reddish or yellowish hue, as the Prophet, peace and blessings be upon him, and Abu Bakr and Umar did.
