If a woman's menstruation is delayed for a month, She should not take medicine to induce her period from the same day, because once the sperm reaches the womb, it becomes a clot, then a lump, then what Allah
سبحانه وتعالى wills. If sperm does not reach the womb, nothing is created from it. Therefore, if her menstruation stops for a month and exceeds the time She used to menstruate, She should not take any medication. If a man purchases a mature female slave and She does not menstruate for six months, and there is no pregnancy and it is common for someone of her age to menstruate, and it is not due to age, this is considered a defect for which She can be returned. A menstruating woman is not required to wash the clothes She wore during her menstruation or sweated in unless they were soiled with blood, in which case She must wash the blood. If blood from menstruation stains her clothing and She washes it but the stain does not go away, She may dye it with a dye (like red ochre) until it blends in. If menstruation stops and the woman dyes her hair with henna, her menstruation may return. There is no harm in a menstruating woman pouring water for someone performing wudu or handing them the prayer mat It is not permissible to have intercourse with a woman during her menstruation, as Allah
سبحانه وتعالى, the Exalted, has prohibited this, saying: 'Do not approach them until they are pure,' [Surah Al-Baqarah
2:222] meaning until they perform ghusl after menstruation. If a man is very eager and the woman has purified herself but not performed ghusl, he may ask her to wash her private parts before intercourse. If a man has intercourse with a woman during her menstruation, he must give charity: a dinar if it is during the beginning of menstruation, half a dinar if it is during the middle, and a quarter of a dinar if it is at the end.
