The rights of wives and husbands are completely described in the Glorious Quran. When studying them one can recognize these mutual rights as being one of the miracles of the pure culture of Islam. No other school of thought has so thoroughly attended to the rights of wives and their husbands until now, and none can do so from now until the end of time. These rights include obligatory and recommended rights. Disrespecting the obligatory rights without the other person's consent is the cause of divine punishment, and not honoring the recommended rights will lessen the sweetness of life. A major portion of these mutual rights are described in Vasa'il al-Shiaa, volumes 20-22, printed by Al-i-Bayt Press. As much as is required, I shall quote traditions from this volume, and instruct my dear readers to carefully read over those volumes.
Firstly, to bless the discussion I shall mention a few Quranic verses related to the matter and then I shall quote the traditions.
I will mislead them, and I will create in them false desires; I will order them to slit the ears of cattle, and to deface the (fair) nature created by God. Whoever, forsaking God, takes Satan for a friend, has of a surety suffered a loss that is manifest. [Holy Quran Nisaa 4:119]
And women shall have rights similar to the rights against them, according to what is equitable: [Holy Quran: Baqara: 2:228]
And yet they had already covenanted with God not to turn their backs, and a covenant with God must (surely) be answered for. [Holy Quran: Ahzab 33:15]
Isaq, the son of Ammac, said that he had asked Imam Sadiq what right does a woman have whose fulfillment by her husband implies that he is a good doer. The Imam replied that he should feed her properly and provide her with clothing. And when she does something out of ignorance, he should forgive her. Then the Imam said my father had a bothersome wife but he would always forgive her. The sixth Imam quoted the Prophet (S.A.W.) as saying: Gabriel recommended on behalf of wives so much so that I thought divorcing her is not permissible unless she commits adultery. He also said good mercy be upon the man who performs all the affairs for himself and his wife well, since God the Almighty has granted to men the control of women, and established the husband as her guardian. The Prophet (S.A.W.) said: One who ignores his wife's rights is deprived of God’s Mercy. He also said: The best of you is one who is the best for his family and I am a model for you in this regard. He also said: A man's wife is his slave and the person most loved by God the Almighty is the one who treats his slaves kindly.
The Rights of the Wife:
1- Providing the means for living.
The Prophet (S.A.W.) said one must provide the foodstuffs and clothing of his wife in the best manner. Imam Sajjad said: Going to the market and buying one Durham of meat which my wife desires is better than freeing a slave. The sixth Imam said: The most fortunate man is the one who manages the affairs of his wife and children.
2- Sexual intercourse.
The eight Imam was asked about a man who had a young wife whom he had not slept with for nearly a year due to a disaster that had come upon him. He had no intentions to bother his wife but the disaster caused him to do so. Was he sinning? The Imam answered: Of course. After four months passed, he was sinning. Abuzar asked the Prophet: Is a man's love-making to his wife divinely rewarded even though it brings pleasure? The Prophet (S.A.W.) answered: Yes, of course. Is it not forbidden to satisfy your sexual desires unlawfully? Abuzar answered yes. Then the Prophet (S.A.W.) said: Certainly its lawful form is divinely rewarded. It is considered desirable in divine teachings for a man to sleep with his wife for love-making once every four nights.
3-Improving the Living Conditions
The Prophet (S.A.W.) said: When a man goes to shop for his wife, he is similar to one who takes charity to the house of the needy. When he gets home, he should first give what he has bought to his daughters. This is so because one who makes his daughter happy is similar to one who frees a slave from Ismael's generation. And one who makes his son happy by giving him something is similar to one who cries for fear of God given that God shall take such a person into Heaven filled with blessings.
Imam Musa said: Men's wives are their slaves. When God gives blessings to anyone he should use it to improve the living conditions of his slave or else that blessing might be taken away from him. The Prophet (S.A.W.) has admonished against a man being full while his wife is hungry. The sixth Imam said: A man should try to do the following things even if it is against his own desires.
(1) Treating the family well
(2) Trying to improve his living conditions without being wasteful
(3) Being concerned about protecting the family's honor.
The fourth Imam said: God is more pleased with the one who brings about more improvement in his family's living conditions. The Prophet (S.A.W.) said: Whatever a Muslim man buys for his wife has a reward similar to that of charity...http://www.imamreza.net/eng/imamreza.php?id=6186
