Abu Sa'id al-Khudri said that when God’s messenger went out to the place of prayer on the day of sacrifice, or on the day when the fast was broken, he came upon some women and said, "Give alms, you women folk, for I have been shown that you will be the majority of the inhabitants of hell.”They asked,“For what reason, messenger of God?”He replied,“You are greatly given to abuse, and you are ungrateful to your husbands. Among women who are deficient in intelligence and religion I have not seen anyone more able to remove the understanding of a prudent man than one of you.”They asked,“What is the deficiency of our religion and our intelligence, messenger of God?”He replied,“Is not the testimony of a woman equivalent to half the testimony of a man?”They said,“Yes.”Remarking that that pertained to the deficiency of her intelligence, he asked,“Is it not the case that when she menstruates she neither prays nor fasts?”When they replied,“Yes,”he said,“That pertains to the deficiency of her religion.”(Bukhari and Muslim.)
