My mother says: If I cut my hair and nails while I am menstruating, I must wash them when I take the full ritual bath for menstruation. Is this correct?

Question:
I hope you will clarify for me how to take the full ritual bath for menstruation, as my mother says it is not permissible for me to cut my nails or hair while I am menstruating, and if I do so, I must keep them until I take the bath so that I can wash them with me. Is there any report of this from the Prophet (peace and blessings be upon him)?

Answer:
This statement is not correct, and there is no report of it from the Messenger of Allah (peace and blessings be upon him). It is merely the talk of common people, or some of them, and it has no basis. It is permissible for a menstruating woman to cut her nails during menstruation, and there is no blame on her for doing so, if Allah wills.
As for the manner of taking the full ritual bath for menstruation, she first cleans herself and purifies the exit from ritual impurity and menstrual blood. Then she washes her head and ensures the water reaches it. Then she pours water over her body three times; this is the most complete way. If she pours water over her body only once, that is sufficient, but three times is better. She starts with her right side, then her left side. Yes.
