It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: "Whoever has intercourse with a menstruating woman, or approaches a woman from her behind, or goes to a soothsayer and believes what he says, then he has denied what was revealed to Muhammad, peace and blessings be upon him." (That is, he has denied the Noble Qur'an.)
