Ruling on dyeing white hair black

A message was received by the program from our sister listener (F. A. A.) from Riyadh. Our sister has a number of questions, and in one of them she says: A woman who is forty-one years old has some white hairs in her hair, and she wants to dye these hairs black to adorn herself for her husband. What is the ruling on that?
Answer: The Prophet (peace and blessings be upon him) said: So it is not permissible for her to dye the white hairs with pure black, but she should dye them with henna that is not black, or with another dye: yellow or red or between black and red, and it should not be pure black at all, and there is no harm in that. As for pure black, no, she is prevented from that. Yes.
The presenter: May Allah reward you with good. Among the women, there is henna they call black henna?
The Shaykh: If it dyes black, do not do it. If it is red or between red and black, there is no harm.
The presenter: May Allah reward you with good, and if its name is black henna?
The Shaykh: And if its name is henna, yes, the criterion is the realities, not the names. Yes.
The presenter: Yes.
