What is the ruling on selling questions to students in various subjects, knowing that these questions are derived from foreign copyrighted books, but have been rephphrased and supplemented with external information? Is it permissible to sell them absolutely, or are there conditions? And what is permissible to take from these books?
There is no objection to selling questions in the manner mentioned, and there is no need to attribute the effort to the original source from which it was benefited, as long as there was no verbatim نقل (transfer/copying) but rather a rephrasing with the addition of other information.
