Praise be to Allah.
The husband has to treat his wife in a good and kind manner, and to spend on her food, drink, clothing and accommodation, because Allah says (interpretation of the meaning):
“and live with them honourably”
[al-Nisa 4:19]
“And they (women) have rights (over their husbands as regards living expenses) similar (to those of their husbands) over them (as regards obedience and respect) to what is reasonable, but men have a degree (of responsibility) over them. And Allah is All-Mighty, All-Wise”
[al-Baqarah 2:228]
Ahmad (20025) and Abu Dawood (2142) narrated that Mu’awiyah ibn Haydah (may Allaah be pleased with him) said: I said, “O Messenger of Allah, what are the rights of the wife of any one of us over him?” He said: “That you should feed her when you feed yourself, clothe her when you clothe yourself, you should not hit her on the face, you should not curse her and you should not forsake her except in the house.”
Al-Albani said concerning this hadeeth in Saheeh Abi Dawood: (it is) hasan saheeh.
The Prophet (peace and blessings of Allah be upon him) enjoined good treatment of women in more than one hadeeth. Hence the husband has to fear Allah with regard to his wife, and give each person his or her rights. Honouring one's parents and upholding the ties of kinship do not conflict with treating one's wife kindly and honouring her and taking care of her. The best that can be mentioned concerning that is the words of the Prophet (peace and blessings of Allah be upon him): “The best of you is the one who is best to his family, and I am the best of you to my family.” Narrated by al-Tirmidhi (3895) and Ibn Majah (1977). Classed as saheeh by al-Albani in Saheeh al-Tirmidhi.
The Prophet (peace and blessings of Allaah be upon him) regarded being kind to one's family as being the criterion with regard to who is best. Whoever wants to be one of the best of the Muslims should be kind to his family, which includes being kind to one’s wife, children and relatives.
The Prophet (peace and blessings of Allah be upon him) said: “You will never spend anything seeking thereby the Face of Allah, but you will be rewarded for it, even (the food) that you put in your wife’s mouth.” Narrated by al-Bukhari, 56.
