"If he beats her, the beatings should not be hard, so that they do not leave a mark. He can beat her with a short rod. He must avoid beating her in the face or in places in the head where it hurts. The beatings should be on the body and should not come one right after the other. These are all choices made during the process, but beatings are allowed only as a last resort. The honoring of the wife in Islam is also evident in the fact that the punishment of beating is permissible in one case only: when she refuses to sleep with him." - Sa’d Arafat
