My mosque has a shelf full of books and i picked a book and started reading it, I really liked it and would like to keep it. I asked my friends if they know if the mosque will let me pay for the book to keep it. One of them said the Imam would give it to me with the intention of gifting it to me. My question is, I heard people donated the books, is it enough to get permission from the Imam if I can keep the book? I think it’s not right because I need more permission from like others because like how did they get all these books? What if I need to get someone else’s permission and not the imam? You know? If he gifts me the book, would I have to ask if they paid khums on it or not? I have a Nahjul balagha; That is volume 1 and 2, I have not read volume 2 but I am in the process of reading volume 1. Would I need to pay khums on the volume 2 book?
