What is the permissibility of reading non-fictional books with the intention of building a stronger vocabulary for the purpose of giving da'wa. Is this considered a waste of time?
Reading Fictional novels I know are pointless, and often of the time they contain much haraam. Not to say that non-fiction books donýt contain haram. But supposing you had a non-fictional book, that didnýt have magic, romance, etc, would it be permissible to read such a novel?
