Dear Mahmoud,

Thank you for your question. Yes, you can cite preprints from arXiv in your paper, but you need to be careful about how you use them. Preprints are okay for talking about new trends or methods that are already known. However, you shouldn’t use them to back up important points or arguments in your paper. Since these papers haven’t been peer-reviewed, they don’t provide strong support for serious claims. For example, if you are discussing a new discovery that goes against earlier studies, and only preprint papers support it, then your discovery isn’t well-supported. You would need papers that have been peer-reviewed to really back up your findings.

Also, it’s not a good idea to rely only on preprint papers for designing experiments or methods, because they haven’t been thoroughly checked yet.

In summary, you can use arXiv papers to add extra information or to show smaller points in your paper, but they shouldn’t be the main evidence for your major findings and claims.
