How is ghusl performed after menstruation in a simplified manner, and what is the meaning of Aisha's hadith regarding that, and is it permissible for a Muslim woman to marry an innovator (mubtadi')?

The sufficient ghusl (ritual bath) is performed with the intention and by ensuring water covers the entire body. The complete and recommended ghusl aligns with the description of the Prophet's ghusl, peace and blessings be upon him. The ghusl for menstruation is like the ghusl for janabah (ritual impurity requiring a bath), except for the obligation of undoing braided hair according to the Hanbalis. It is sunnah for a woman to use a piece of cotton with musk to trace the اثر of blood. If she does not find musk or if it is harmful, she should use another perfume; otherwise, water is sufficient. A woman must avoid marrying an innovator and seek a man of religion who adheres to the Sunnah.
