What is the ruling on a Muslim woman marrying a Muslim man while she is pregnant by her non-Muslim husband, whom she left immediately after her conversion to Islam, and then she married the Muslim man before the 'iddah period ended? And what is the ruling on a Muslim woman not wearing the niqab if her husband obliges her to wear it, but she is not ready for it?

If the wife embraces Islam while her husband remains a disbeliever, she becomes unlawful for him, and the separation between them depends on the completion of her iddah (waiting period). If the husband embraces Islam before the iddah ends, the marriage remains valid. However, if the iddah ends before he embraces Islam, the wife is considered free and may marry whomever she wishes.

If the wife marries before the completion of her iddah, her marriage is void. She must immediately separate from the second husband, complete the iddah for the first husband, then observe an iddah for the second husband, after which she may marry whomever she wishes.

Furthermore, a woman must cover her entire body from non-mahram men.
