What was narrated to me by the Shaykh from Ahmad bin Muhammad, from his father, from Al-Husayn bin Al-Hasan bin Aban, from Al-Husayn bin Sa'id, from Al-Qasim, from Ali bin Abi Hamzah, from the Righteous Servant عليه السلام of Allah سبحانه وتعالى: A slave woman of his father عليه السلام asked Imam عليه السلام and said: "May I be sacrificed for you. I want to ask you about something, but I feel shy about it." Imam عليه السلام said: "Ask me, and do not feel shy." She said: "Menstrual blood stained my garment, and I washed it, but its traces did not go away." Imam عليه السلام said: "Dye it with mishq (a type of dye) until it blends in and the trace disappears."
