Is it permissible for a married Muslim woman to leave her house alone to attend a Qur'an memorization circle, and what are the conditions and regulations for her going out, and is it permissible for her to ride mixed public transportation?

It is permissible for a woman to go out to attend a Quran memorization circle or for other permissible matters, provided that she goes out veiled, not adorned, and not perfumed, and with her husband's permission if she is married, and that she is safe from temptation. It is permissible for her to ride public transportation provided that there is no fear of temptation and no close contact with men; otherwise, it is not permissible for her to go out.
