I want to know the answer to the following question:
When was formal education for Islamic women halted?
All the background I'm provided with is that "Another feminine figure to be remembered for her achievements was Tawaddud, "a slave girl who was said to have been bought at great cost by Hārūn al-Rashīd because she had passed her examinations by the most eminent scholars in astronomy, medicine, law, philosophy, music, history, Arabic grammar, literature, theology and chess".". Is that enough to answer the question?
Answer: no
