A pious woman's priority is to seek the pleasure of Allah. She tries acquiring the qualities of a good wife by following the examples set by the Prophet (Sallallahu alaiyhi wassallam - may the peace and blessing of Allah be upon him), and obeying what is commanded in the Book of Allah. Complete obedience and adherence to the Sunnah of the Prophet (Sallallahu alaiyhi wassallam) and Quran is the best of a woman's qualities.
A woman is married for four reasons: for her wealth, for her fame, for her beauty and for her religion. So marry one for her religion and you will be successful. [Bukhari & Muslim]
Therefore the righteous women are devoutly obedient (to Allah and to their husbands) and guard in their husband's absence what Allah orders them to guard (e.g. their honor, husbands property, etc) [4:34]
An-Nasaii narrated that the Prophet(Sallallahu alaiyhi wassallam) was asked "Who are the best of women?" He replied, "The one who pleases him (her husband) if he looks at her, obeys him if he asks (her) and does not subject her honor or money to what he dislikes."
Ibn Hibban narrated that the Prophet(Sallallahu alaiyhi wassallam) said, "If a woman prays her five prayers, fasts in Ramadan, protects her honor and obeys her husband; then she will be told (on the Day of Judgment): enter Paradise from any of its(eight) gates that you wish."
If a woman harms (in any way) her husband, then his wife in Paradise tells her: "Do not harm him, May Allah fight you, he is only staying temporarily with you. Soon he will come to us." [Ahmad & At-Tirmithi]
If a man calls his wife to bed and she refuses till he slept while angry, then the Angels will curse her till the morning. [Muslim]
Allah does not look to the woman who does not appreciate her husband while she cannot stand his departing her. [An-Nasaii].
Any woman who asks her husband for divorce for no reason will not smell the fragrance of Paradise. [Sahih Al-Jamii]
The Prophet (Sallallahu alaiyhi wassallam) said, "If I were to order anyone to bow down to other than Allah, I would order the wife to do so for her husband. By the One who owns the soul of Muhammad, if a wife does not fulfill her obligations towards her husband, then she will not have fulfilled her obligations towards Allah." [Ahmad]
