Muslim scholars have stated that observing the fast is forbidden for menstruating women. However, when a woman's period has ceased, she must bathe and continue fasting. Any fasts broken or missed due to menstruation must be made up whenever she can before the next month of Ramadan. Women must fast at times when not menstruating, as the Quran indicates that all religious duties are ordained for both men and women. The reason for this is because the Quran refers to menstruation as "Say: It is a discomfort(Menstruation)" According to Nouman Ali Khan an Islamic speaker in the United States the reason for this prohibition is because of the pain associated with it. A Muslim woman may still do dhikr (remembrance of Allah) and make dua (supplication to Allah) during this time.
