But if a man be just, and do that which is lawful and right, and hath not ... come near to a menstruous woman.... Ezekiel 18:5
They question thee (O Muhammad) concerning menstruation. Say: It is an illness, so let women alone at such times.... Quran 2:222
Finally, a topic upon which Muslims, Christians, and Jews can fully agree! Women are unclean when menstruating and men should stay the hell away from them.
Here's what the Bible has to say. (A women who is menstruating is unclean and should be kept away from everyone else for seven days. Whatever she touches or sits on is unclean. Whoever touches a such a women is unclean. Whoever touches her bed is unclean. Whoever touches anything that she sits on is unclean. And anyone who has sex with a menstruating woman is really unclean -- unclean for seven days.)
And if a woman have an issue, and her issue in her flesh be blood, she shall be put apart seven days: and whosoever toucheth her shall be unclean until the even. And every thing that she lieth upon in her separation shall be unclean: every thing also that she sitteth upon shall be unclean. And whosoever toucheth her bed shall wash his clothes, and bathe himself in water, and be unclean until the even. And whosoever toucheth any thing that she sat upon shall wash his clothes, and bathe himself in water, and be unclean until the even. And if it be on her bed, or on any thing whereon she sitteth, when he toucheth it, he shall be unclean until the even. And if any man lie with her at all, and her flowers be upon him, he shall be unclean seven days; and all the bed whereon he lieth shall be unclean. Leviticus 15:19-24
The Bible goes on and on about this, but I think you get the idea. Finally the woman is allowed back into society, when on the eighth day she goes to the priest and sacrifices two pigeons or two doves ("turtles" in the KJV) as a "sin offering" -- "an atonement for her before the LORD for the issue of her uncleanness."
But if she be cleansed of her issue, then she shall number to herself seven days, and after that she shall be clean. And on the eighth day she shall take unto her two turtles, or two young pigeons, and bring them unto the priest, to the door of the tabernacle of the congregation. And the priest shall offer the one for a sin offering, and the other for a burnt offering; and the priest shall make an atonement for her before the LORD for the issue of her uncleanness. Leviticus 15:28-30Other passages in the Bible also address menstruation, but this is one of the few topics upon which the Bible speaks consistently and clearly. (Except for the punishment of having sex with a woman during her menses.)
Also thou shalt not approach unto a woman to uncover her nakedness, as long as she is put apart for her uncleanness. Leviticus 18:19In other places, the Bible refers to menstruation in ways that show how God sees it.
And if a man shall lie with a woman having her sickness, and shall uncover her nakedness; he hath discovered her fountain, and she hath uncovered the fountain of her blood: and both of them shall be cut off from among their people. Leviticus 20:18
Let it not displease my lord that I cannot rise up before thee: for the custom of women is upon me. Genesis 31:34-35
Thou shalt cast them away as a menstruous cloth. Isaiah 30:22
Jerusalem is as a menstrous woman. Lamentations 1:17
They humbled her that was set apart for pollution. Ezekiel 22:10
The Quran says it all in just one verse, but it is in complete agreement with the Bible.
They question thee (O Muhammad) concerning menstruation. Say: It is an illness, so let women alone at such times and go not in unto them till they are cleansed. And when they have purified themselves, then go in unto them as Allah hath enjoined upon you. 2:222
Menstruation is a sickness. Menstrating women are unclean. Stay away from them while they are menstruating. And, for God's sake, don't have sex with them!
