Is it permissible for a pregnant woman in her fourth month, whose husband forbids her from fasting out of fear for her and their child, to disobey her husband and fast, and should she perform Tarawih prayers if she breaks her fast?

Pregnancy in itself is not an excuse that permits breaking the fast. If the pregnant woman does not fear harm to herself or her fetus, it is not permissible for her to break the fast. However, it is permissible to break the fast if she knows or strongly believes that she or her fetus will be harmed by fasting. This can be known through experience, strong presumption, or the report of a trustworthy female doctor. It is not permissible for a pregnant woman to obey her husband in breaking the fast if breaking the fast is not legally permissible. She can perform Tarawih prayers, and she will have a great reward for that.
