They ask you about menstruation? Say, "It is painful; so retire yourselves sexually from the women during the menstruation, and do not approach them until they are cleansed. When they are cleansed, then you may approach them as God has commanded you." God loves the repenters and He loves the cleansed.

[2:222] Prohibition of sexual intercourse during menstruation is for the protection of women from pain and potential infection. Other than that, menstruating women should continue their contact prayers, charity work, fasting, and studying the Quran. Commentaries based on hadith and sunna, not only mistranslate the word tahara but also fabricate a list of prohibitions for women claiming that they are not worthy of communicating with God or performing some good acts. In verse 3:55, the word tahara means "to be rescued" or "free from." Despite the Quranic rule, the followers of hadith and sunna adopted Jewish laws that consider women unclean, and treat them like dirt for fourteen straight days of every month. According to the fabricated rules of the Old Testament, a menstruating woman is considered unclean for seven days, and during that period wherever she sits will be considered unclean; whoever touches her or sits where she sits must wash and bathe. After she finishes the menstruation, she has to wait for seven more days to be considered clean for ceremonial purposes (Leviticus 15:19-33).
