A competition for purchasing religious books with prizes

Question:
Is it permissible to hold a competition for purchasing religious books? A competition for purchasing religious books, meaning that the bookstore or the person who prints the book places questions on it so that people buy these books, then they solve these questions and there are prizes for them, so that they benefit from purchasing the book and making use of it, or is it not permissible because they are buying what they do not need?

Answer:
If the books are beneficial, if the books are beneficial to him in his religion, and the owner of the book has attached to them beneficial, legitimate religious questions with prizes, then there is no harm in that, because this is part of seeking knowledge, and seeking and taking prizes in religious competitions. Ibn al-Qayyim (may Allah have mercy on him) mentioned that it falls under jihad in the path of Allah, it falls under jihad in the path of Allah.
