Is it permissible to distribute a lesson, purchased for a sum of money, to friends for free after buying it?

It is permissible to attend courses and training programs for a fee, and it is permissible for whoever owns the actual object or its usufruct to benefit from it for himself or for others. The general principle is that copyright and invention rights are protected by Islamic law. It is permissible to distribute the training course material to a limited number of friends for free, and it is permissible to sell the original copy that was purchased. However, copying the material and selling copies of it is not permissible if its owners have prohibited it, unless the copying is for personal use and not for commercial purposes.
