Feed and clothe your wife to the same standard as yourself never strike her face or cut her with words The Prophet (PBUH) never beat any of his wives or servants; in fact he did not strike anything with his hand except in the cause of Allah or when the prohibitions of Allah were violated, and he retaliated on behalf of Allah. never estrange yourself from your wife except within the house. It is not lawful for a woman who believes in Allah to allow anyone in her husband's house while he dislikes it, nor should she beat him. If he is more in the wrong then she, she should plead with him until he is reconciled. If he accepts her pleading, well and good and her plea will be accepted by Allah; while if he is not reconciled with her, her plea will still have reached Allah in any case.
