The relation between some religions (Christianity and Islam) and marital rape is controversial. The Bible at 1 Corinthians 7:3-5 explains that one has a "conjugal duty" to have sexual relations with one's spouse (in sharp opposition to sex outside marriage, which is considered a sin) and states, "The wife does not have authority over her own body, but the husband does. And likewise the husband does not have authority over his own body, but the wife does. Do not deprive one another..." Some conservative religious figures interpret this as rejecting to possibility of marital rape. Islam makes reference to sexual relations in marriage too, notably: "Allah's Apostle said, 'If a husband calls his wife to his bed (i.e. to have sexual relation) and she refuses and causes him to sleep in anger, the angels will curse her till morning';" and several comments on the issue of marital rape made by Muslim religious leaders have been criticized.
