I am not referring to blasphemy or the likes as Salman Rushdie was accused of. Rather I am inquiring about basic fiction writing. As an English major I would like to know what I can and cannot do in writing about things other than religion.
Writing of fictions or novels is permitted provided they do not go beyond the bounds of shari'a. So, for example, writing a novel which could clearly lead to lustful thoughts or acts is haram, so is writing any form of material which is insulting to Islam or God, the Prophets, and Imams.
