Is drawing cartoon characters using Photoshop to create educational videos and stories of the prophets for children impermissible (haram)? And is it impermissible (haram) to use stories from books found online to make videos without citing the source, while promoting the purchase of these books?

It is permissible to produce purposeful animated films due to their predominant benefit, provided that prophets are not depicted.

Copyrights are protected for their owners, and it is not permissible to infringe upon them. Converting a written text into a visual work is considered an infringement without the author's permission. However, mere quotation is permissible provided that attribution is given to the original author. Promoting a book does not justify converting its texts into videos, nor quoting without attribution.
