To Marry as soon as able to.
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.
"Consort with your wives in kindness, for if you dislike them, it may
be that you dislike something in which Allah has placed much good."
--The Holy Qur'an 4:19
