It is not permissible for a woman to prevent her husband from having intercourse with her without a legitimate excuse such as menstruation or childbirth, and if she does, then she is a sinner, and it is permissible for him to force her to have intercourse, because that is one of his rights, rather all his rights are limited to two things, namely intercourse at any time, and not leaving the home without his permission. I do not mean by forcing to cause physical harm to her, which is of course forbidden, but he can force her by not spending on her – for example – as long as she is abstaining, or prevent her from leaving the house, or threaten her to marry another woman.
