Chapter on the Rules of Menstruation, Istihadah, and Nifas, and Purification From Them

The Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, said: It is recommended for a menstruating woman to perform ablution (wudu) at the times of prayer and sit in a separate area of her prayer space to glorify Allah سبحانه وتعالى, praise Him, declare His greatness, and engage in His remembrance, for the duration equivalent to the time of her prayer at each prayer time.
