The relationship between the husband and wife is a very tender, loving and pure relationship. They are in reality the "garb" of one another. Thus, it is the duty of each to be protective over the life, property and modesty of one another. It is necessary for them to realise and understand their mutual duties as a couple. They are two bodies joined by the soul.
The Prophet (sallal laahu alaihi wasallam) has stated that if a husband was pleased and content with his wife when she passed away, then she will enter Paradise. The explanation of one Hadith is that if a husband passes the night displeased with his wife, she invokes upon herself the Curse of Allah and the Angels. In another hadith, the Prophet (sallal laahu alaihi wasallam) said, "If I had commanded prostration for any other than Allah, I would have commanded the wife to make Sajdah to the husband." However, since Sajdah is none but for Allah, a woman cannot prostrate to her husband but she should be obedient towards him.
The husband is the provider and protector of his wife. He should thus fulfill her needs and keep her pleased. "The best from amongst you is he who is best to his wife." (Hadith) If there is a conflict, the husband should not be hasty to give her Talaaq (Divorce), but should cool his temper, think carefully and take the opinion of elders before making any decisions as Talaaq is not something which is liked. The Prophet (sallal laahu alaihi wasallam) has stated: "From those actions that are Halaal, the most disliked is Talaaq."
The wife should also be patient with the husband. She should show her gratitude for anything that he does. She should understand him and not be lavish with his wealth. She should always be neatly attired and loving. She should love and respect his family. That house in which there is daily conflict is living hell and that home in which there is love and respect is a blessed home.
The Laws of Shari'ah: If a man passes away, the wife may give him Ghusal, but the husband cannot give his deceased wife Ghusal, nor can he touch her deceased body without a cloth. He can, however, see her face. It is common in the public that the husband cannot carry the wife's Janazah or lower her into the grave. This is false. He may see her face, carry her Janazah and lower her into the grave.
