What is the ruling on reading a book with good content and a good author, after the buyer becomes aware that the publishing house publishes reprehensible books?

Wisdom is the lost property of the believer. There is no harm in reading and purchasing good, beneficial books, regardless of the overall content of the publishing house, as long as the transaction itself is permissible. The key lies in the type and content of the transaction. The reader must distinguish between the valuable and the worthless, or seek guidance from someone who can direct them.
