Is it permissible to copy and publish religious articles and Sayings (Ahadith) from the internet, and is it necessary to mention their original source (the website)?

It is permissible to publish articles from the internet if they are free from Sharia prohibitions, and this is not considered an infringement on the rights of others; because publishing on the internet is often intended for general benefit. It is desirable to attribute the article to its source if it is a beneficial website, in order to guide others to it.
