Is it permissible to continue an electronic project for disseminating religious knowledge (for free) by scanning and uploading books, given the issue of copyright and the refusal of some publishing houses, and does the benefit of disseminating knowledge take precedence over copyright?

The author has two rights regarding their work: a material right and a moral right. The material right is reserved for the author and passes on to their heirs. It entails that no one may copy or print the work except with their permission.

If a book is devoid of a specific permission for copying, this indicates the author's permissibility for the public to benefit from their book, as the primary purpose of authorship and publication is public benefit.

Authors usually intend to prohibit commercial copying and printing, not personal copying for study or non-commercial use.

Some scholars have permitted copying for non-commercial benefit, but it is more prudent to limit copying to books whose authors have not reserved their publishing rights.
