Is a married woman punished for admiring three specific men, where she is happy to see them by chance without disclosing her feelings to them or being infatuated with them, and without seeking to see them?

You must be mindful of Allah Almighty in your every movement and stillness, and avoid every place where an encounter with men might be suspected. You should know that admiration can be fostered by Satan to make you disdain what is lawful and desire what is unlawful. You must strive against your soul to stop thinking about these men, and occupy yourself with beneficial knowledge and deeds, serving your husband, and caring for your children. If you do this, you will not be blamed thereafter for the inclination of the heart and the fleeting thoughts of the soul.
