In Islam, if a Husband calls his wife to his bed and she refuses and causes him to sleep in anger, the angels will deal with her mercilessly till morning.By the One in Whose Hand is the soul of Muhammad! No woman can fulfill her duty towards Allah until she fulfills her duty towards her husband. If he asks her (for sex) even if she is on her Camel Saddle, she should not refuse.[Sunan Ibn Majah,
