What is the ruling on a husband's refusal to engage in sexual intercourse, and the resulting coldness and ill-treatment of his wife, who adorns herself for him but receives no attention from him? And is the wife entitled to seek divorce if this situation persists?

It is obligatory for the husband to treat his wife with kindness, and this includes fulfilling the wife's right to conjugal relations, which is one of her most emphasized rights upon him. Scholars have differed on the period during which a husband must have intercourse with his wife, and the preponderant opinion is that it depends on her need and his ability. Some jurists have stated that a man must have intercourse with his wife once every four nights if she complains about the infrequency of intercourse. If the husband is unable to have intercourse due to health reasons and refuses treatment, the wife has the right to seek a divorce or to be patient with him.
