"According to Hanafi jurists, husbands were required to discipline wifely nushuz; they could discipline their wives physically, and there was a great deal of leeway in the extent and severity of hitting permissible to them. Though they offered moral exhortations to husbands to live with their wives in kindness and equity, Hanafi jurists maintained the principle set out by Ahmad b. Ali al-Jassas that there is no retaliation (qisas) in marriage, except in the case of death. A husband was permitted to hit his wife without any liability, even if the beating resulted in wounds or broken bones, as long as he did not kill her."
