Book of Maintenance (1)
A husband is obliged to provide his wife with adequate food, condiments, clothing, housing, and all related necessities, in a manner appropriate to her station. If the two disagree, a judge will assess the matter in light of their respective means.

He must also cover the cost of her personal hygiene, supply a servant if women of her class customarily have one—even a hired servant—and arrange for a companion when she requires one. The same entitlement applies to a wife in a revocable divorce during her waiting period, but not to an irrevocably divorced woman who is not pregnant, nor to a widow, whose upkeep comes from the estate.

No maintenance is owed to a woman who is imprisoned—even unjustly—or who is recalcitrant, or who undertakes voluntary fasting or Hajj without his permission, or who travels for her own purposes, even with his permission.

(2) Daily maintenance falls due at the start of each day, and clothing at the beginning of every year. If the spouses agree to advance, postpone, or substitute it, that is permissible. One who refuses to pay cannot be compelled, yet the wife’s right does not expire with the passage of time, unlike the support owed to relatives.

Her entitlement arises once she takes up residence with him (3) or makes herself available, even if the husband is still a minor. Whenever he is unable to supply food (4) or clothing, or is absent, and provision cannot be obtained from his assets or through borrowing on his behalf, she may petition a judge to dissolve the marriage.
