Assalamu alaykum wa rahmatullaahi wa barakaatuh, ya Ustadh. May Allaah preserve you. Is it permissible for a woman (married or unmarried) to have an Udtadh who teaches her Qur'aan/Islamic studies? Wouldn't it be for her to find an Ustadha? Also, casual conversations are unfortunately taking place.

No, this is not allowed and it causes fitna. She finds a female teacher to teach her.
