Is it permissible for me to download paid audio lectures and benefit from them for free, especially if they are available on other websites, knowing that I cannot afford their price due to economic sanctions?

The fundamental issue of intellectual and literary rights for authors is a matter of disagreement among scholars. Some have adopted the view that personal use is permissible without the author's permission, provided it is limited to what is needed and no profit is made from it, especially for students of knowledge who require it and are unable to obtain original copies due to their unavailability or their financial inability. This opinion allows the questioner to act upon it given his circumstances.
