How can I preserve my faith during menstruation, knowing that I feel a weakening of faith and a laxity in some matters due to the overwhelming influence of Satan, which causes me sadness and regret?

Menstruation is something God has decreed for the daughters of Adam. A menstruating woman is prohibited from prayer, fasting, and circumambulation (Tawaf). However, she should not abandon other acts of worship and obedience. Rather, she can study Islamic knowledge, perform unrestricted and restricted adhkar (remembrances of God), sit with righteous people, read books of Tafsir (Quranic exegesis), Hadith, and Sirah (Prophetic biography), increase in charity, and benefit people, all while completely avoiding sins and seeking God's help against Satan.
