Is it permissible to oblige a fiancée to wear the niqab and then remove it upon entering school due to the presence of male teachers, knowing that she will become a wife after one year and four months, and that Al-Azhar prohibits the niqab in preparatory and secondary stages?

Upon reaching puberty, it is obligatory for a woman to wear the legal hijab that covers the entire body. The niqab is not prohibited unless its use leads to lawful harms. If she is prevented from wearing it in her place of study, there is no justification for abandoning it elsewhere. It is recommended to wear the niqab and cover the face, as it is more protective for the woman, purer for the hearts of men, and more effective in preventing temptation.
