A:
It is unobjectionable that a woman studies the fields of knowledge beneficial to her as far as her religion and worldly life are concerned. She may do so when her circumstances permit, provided that modesty and non-mixing with men is observed. (Part No. 12; Page No. 175) This is regardless of whether or not her husband, while he was alive, forbade her from this and was dissatisfied with it. In fact, he has no authority over her after his death.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
