Al-Husayn ibn Sa’id narrated from Fadalah, from Abu Al-Mi’za, from Ali, from the Righteous Servant عليه السلام (of Allah سبحانه وتعالى), who said: I asked Imam عليه السلام: "Can a man apply dye while in a state of janaba (ritual impurity)?" Imam عليه السلام said: "There is no harm in it." I also asked about a woman applying dye while she is menstruating. Imam عليه السلام said: "There is no harm in it."
