Why the muslims feared that educated women would be corrupted by reading?

Conservative Hindus believed that a literate girl would be widowed and Muslims feared that educated women would be corrupted by reading Urdu romances. Sometimes, rebel women defied such prohibition. We know the story of a girl in a conservative Muslim family of north India who secretly learnt to read and write in Urdu. Her family wanted her to read only the Arabic Quran which she did not understand. So she insisted on learning to read a language that was her own. In East Bengal, in the early nineteenth century, Rashsundari Debi, a young married girl in a very orthodox household, learnt to read in the secrecy of her kitchen. Later, she wrote her autobiography Amar Jiban which was published in 1876. It was the first full-length autobiography published in the Bengali language.
