"It is not for the woman to spend anything from her wealth, except with the permission of her husband."
(Silsilah al-Ahaadeeth as-Saheehah 2/338 #775)
Shaykh Al-Albaani (may Allaah have mercy upon him) said:
"It is not befitting for the husband, if he is a true Muslim, to take advantage of/misuse this ruling therefore transgressing against his wife, preventing her from spending her wealth in that which there's no good upon her from him. Therefore, if her husband transgressed against her and prevented her from spending her money in a manner that is legislated, then the judge is to straighten out the affair and give her justice."
