Hello!
Thanks for getting in touch with us. My Name Is Muhammad.
I am sorry but there is no demo in Arabic.
-You will have to import any demo you desire.
-Then you can translate your setup to Arabic.
– Please select your language Arabic from the wp-admin>>settings>>general
-Please use a translation plugin like WPML and Polylang. they are very popular and most used for translation.
Further on how to translate the website please check:

Please let me know if you see any issues or need any help.
Thank you!
