Abu Sa’id Al-Khudri related … The women asked: And what is the deficiency in our religion and our intellect, oh Messenger of Allah? He said: Is not the testimony of a woman like half the testimony of a man? They said: Yes indeed. He said: And that is the deficiency in her intellect; is it not true that whenever a woman menstruates, she has not prayed nor fasted? They said: Yes indeed. He said: And that is the deficiency in their religion.
