Praise be to Allah.
Before marriage, a woman is under the guardianship of her father, so it is not permissible for her to go out of the house except with his permission, whether it is to go to the mosque or elsewhere, because obedience to one’s father is obligatory so long as it does not involve disobedience towards Allaah. We advise you to listen to broadcasts from the Al-Qur’aan Al-Kareem station, because there is much knowledge and sound teaching to be gained from it. They have a program called “Noor ‘ala’l-Darb (Light on the Way)” in which a group of scholars answer questions from listeners. May Allaah help you to do all that is good and grant you a sound understanding of Islam.
