To all the Iranians and non-Arabs who have commented here and meddled their ugly noses in Arab affairs they have no business in, made threats and insulted Arabs etc. I have a little message for you.
First of all I will not fall for cheap provocations that will get me banned although it would take me a few seconds to put posts/users as that in their rightful place.
Anyone who has studied the actual works of Ibn Khaldun (who was an Arab btw) in his native language (Arabic) would know that this description was used for the Bedouin tribes who rebelled against local Arab rulers at that time. When Ibn Khaldun was alive the Arab world had the biggest cities in the world together with those found in India/China who always were populated in great numbers. Makkah, Madinah, Sana'a, Baghdad (founded by Hejazi Arabs and the Arabian elite) together with Damascus were among the most populous and thriving places of trade. Not to mention the new cities the Fatimid Dynasty (another Arabian dynasty) built in Egypt that was sparse inhabited at that time. Cairo one of them.
Yemeni history and civilization is among the oldest in the world. In fact the first civilization known to human mankind outside of Africa was first established in Yemen and Hejez. Queen Sheba already ruled a vast empire and the Kingdom of Saba' had built one of the architectural wonders of the ancient world (Marib Dam) nearly 3000 years ago before anything was called Iran and while the Persians still lived as nomads on the Kazakh steppes. She is mentioned in the Torah that dates back to 1000 BC. Way before any other known Queens. Oman and especially Hejaz have ancient civilizations as well.
Eastern KSA, Bahrain, Qatar had Dilmun a empire that predated any of Iran and which was a trading partner of Mesopotamia and the Indus Valley.
Anyway Semitic people have the oldest civilizations outside of Africa.
The second description is ludicrous. The Arabs conquered half of the world in a few decades through military brilliance. Including Iran with ease despite being outnumbered at first. And unlike Iran we established our empire in Europe as well for CENTURIES and from the Atlantic Ocean to the Arabian Sea.
Arabic grammar was already established WAY before Islam in Hejaz and Yemen so that's also a lie. No Iranian presence in those areas - EVER..
Even "only" 1000 years before Islam ancient Arabian kingdoms in KSA, Syria, Jordan and Iraq built World UNESCO Heritage Sites such as Petra, Mada'in Saleh, Palmyra and Hatra.
Even a Roman Emperor (Philip the Arab) became a Roman Emperor.
The stupidity even reaches another pathetic low considering the fact that the Caliph Harun al-Rashid (half Hejazi and half Yemeni) was the most successful patron of the arts/culture in the Middle Ages and constructed the largest library (Bayt al-Hikma) known in the ancient world.
Bunch of cheap air but provocateurs with inferiority complexes who don't know anything about Arab/Semitic history nor speak the language will always make trouble. But this is expected when seeing the messenger. It gets even more funnier when it comes from a half Kurd (do you guys even have a civilization - not a country that's for sure) and a Persianized Azeri/Gypsy or any other minority group in Iran that make up the majority of the population.
Checkmate.
