All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
The wife has the right to spend her money as she pleases in what is permissible and she is not obliged to seek the permission of her husband in doing so; we have already clarified this in Fataawa 86496 and 84249. Therefore, your husband has no reason for getting angry with you because of not seeking his permission. However, if seeking his permission comforts him, then you should seek his permission. Moreover, if buying some items for your children requires going out of the house, then you are obliged to seek the permission of your husband when going out, because it is not permissible for a wife to go out of her husband’s home without his permission.
Moreover, it is permissible for the husband to turn his back to his wife in bed if she is disobedient but he should not prevent her from her right in spending the night with her. Of course, this applies to a disobedient wife, but not with a woman who did not do anything that suggests being disobedient, rather she acted in what was permissible for her to do.
For more benefit, please refer to Fataawa 83631 and 82124.
Finally, we advise both of you to take it easy in all your affairs and be wise in solving any problem that may occur in your marital life, far from being stubborn and angry.
Allaah Knows best.
