When a girl reaches puberty, it is obligatory on her to wear the clothes that cover all her `Awrah (parts of the body that must be covered in public), including her face, head, and hands, whether she is a student or not. (Part No. 17; Page No. 220) It is the responsibility of her guardian to make her abide by this, even if she does not like it. He should also train her for this duty before she reaches puberty, so she will get used to it and it becomes easy for her to comply. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
