Under the pressure of the school management and her family she took off the Hijab
Hijab is an obligation according to the Shari`ah (Islamic law). A Muslim woman should not expose her body and ornaments including the face and hands in the presence of any Ajnaby (a man other than a spouse and a permanently unmarriageable relative). Thereupon, when you wear the Hijab, you follow a prescribed obligation and so it is not permissible for a Muslim who believes in Allah and the Last Day to object to your wearing it. You should be patient anticipating Allah's Reward and try to convince anyone who objects to you of this obligation and supporting your argument with evidence and leniency. May Allah grant you success and guide you to good and righteous deeds.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
