Is dyeing a white beard for the purpose of marriage, with a color other than black, considered deception of the wife and her family?

It is recommended to dye gray hair with a color other than black, in order to differ from the Jews and Christians, and to avoid black. It is not permissible to deceive or mislead during a marriage proposal by dyeing gray hair black or a color close to it, such that the matter becomes ambiguous and it is assumed that there is no gray hair. This is due to the Prophet's (peace be upon him) saying: "Whoever cheats is not of me." So, either leave the dyeing so that the gray hair is visible, or inform them about it, or dye it with red or yellow so that the matter is not ambiguous to whoever sees you.
