My husband had intercourse with me on my menses mid cycle although my bleeding had stopped a day before but it was my 5th day of cycle and i hadn’t took ghusl. Is this act unlawful according to sistani

If the menstrual blood has stopped, and there is no blood in the inside of the vagina, then it is permissible to have intercourse before washing, but you need to wash the place of blood before intercourse.
