How to perform the ritual bath for menstruation and major ritual impurity

At the end of her letter, she asks about how to perform the ritual bath for menstruation and for major ritual impurity using modern bathing methods such as the shower, the tap, and others?
Answer: First: a person performs istinja' (cleaning oneself after relieving oneself); the woman performs istinja' from her menstruation and post-natal bleeding, and the man in a state of major ritual impurity and the woman in a state of major ritual impurity perform istinja' and wash the area around the private parts of any traces of blood or other substances, or traces of pre-seminal fluid or semen, removing what is there and the traces of urine. Then each of them performs wudu' (the ablution for prayer) for prayer; the menstruating woman, the woman with post-natal bleeding, and the person in a state of major ritual impurity perform wudu' for prayer. Then, after that, he pours water over his head three times, then over his body, the right side then the left side, then he completes the bath. This is the sunnah (recommended practice); this is the best. If he pours water over his body once, that suffices him and his bath for major ritual impurity and menstruation is valid. However, the detailed method, as mentioned earlier, is better: that after performing istinja', he performs wudu' for prayer, then pours water over his head three times, then washes his right side then his left side, then completes his entire body. This is the best; this is the perfection. As for the woman, if she is menstruating, it is recommended (mustahabb) for her to put suds (soap) in the water; with water and suds, this is the best for the bath for menstruation and post-natal bleeding. As for the person in a state of major ritual impurity, no, he does not need suds or anything else; rather, water is sufficient, whether he bathes from the tap, from the pump, or bathes with the shower, or bathes by scooping water from a pool or a vessel; all of it is permissible (ja'iz), praise be to Allah.
