Is the content of videos and the money earned from publishing them considered unlawful if the content (cooking recipes and mixtures) is taken from websites without the permission of the unknown original author, knowing that these recipes are widespread and repeated on hundreds of websites?

It is permissible to earn money by uploading permissible and unprotected clips to YouTube and similar platforms, provided that the advertisements are also permissible. There is no harm in transferring content from websites unless there is a prohibition on publishing it, and it is recommended to cite the source. As for protected materials, it is not permissible to publish them without the permission of their owners.
