What do nafkah zahir and nafkah batin mean?

Material maintenance is the wife's material needs, while intimate maintenance is the need for affection and marital intimacy.
Material maintenance (nafkah zahir) covers food, clothing, housing and other basic needs according to the husband's means and local custom. Allah says the father must bear the food and clothing of the wife in a reasonable manner. Intimate maintenance (nafkah batin) refers to intimacy, affectionate treatment, attention and time together. The Prophet ﷺ mentioned that a husband's intimacy with his wife also counts as charity. Both are the wife's rights; neglecting either can be an injustice and in certain circumstances can be the basis of a claim at the Syariah Court. See Maintenance and Glossary.
