Learning a few Quranic verses in elementary school and later forgetting those few sentences is hardly ''learning Arabic'' my uncultured camel Bedouin friend.
Persians influenced Arabs and Islam much more. Most of the brilliant Islamic era scholars in the past are of Persian origin. On top of giving life and colour to Islam as a religion the Iranians also preserved their own national identity.. keeping their language, cultural traditions etc until this date.
In your own country, Iraq, a large part of your population, celebrate the Iranian new year Nowruz and other festivals. Who influenced who?
Many Iraqi Arabs can speak Persian too.
Iranian culture today is present in India,Pakistan,Afghanistan,Tajikistan, Uzbekistan, Azarbaijan, Iraq etc
We are getting off topic mate. Let me raise my fine Persian Shirazi wine in your honor.. you can have your camel urine. Cheers.
