 Precaution demands that a woman must not leave her house or get a job outside the house without her husband's permission Also, she must not refuse to have intercourse with her husband without a religiously warranted reason Of course, she does not need to get her husband's permission to go out of the house to do something that is obligatory on her like going to the mosque to learn Islamic laws or to do some necessary things such as doing the necessary shopping for the house, seeing a doctor, etc. It is an obligatory duty of the husband to provide his wife with food, clothes, a house and the other requirements of life based on what is considered normal and usual He must even pay for the doctor or medicine if she needs them If the husband does not do that, even if he cannot afford them, he is considered to be in her debt according to precaution Two important points First, if the wife has a job and an income of her own, she does not need to get her husband's permission about how to spend her income And second, the exorbitantly high amounts of mahr which are clear to have been set with no intention of ever being paid are invalid Similarly, unusual mahrs like one of the limbs of the husband are also invalid and instead of all of them, Mahr al-Mithl needs to be paid However, in both cases, the marriage is valid
