What Arabs were like without Islam?

Better than they are now, that's for damn sure.

Desert Tent dwellers

Certainly did Allah confer [great] favor upon the believers when He sent among them a Messenger from themselves, reciting to them His verses and purifying them and teaching them the Book and wisdom, although they had been before in manifest error. [Quran 3:164]

the arab copied pre Islamic law into Islam and called it holy this how they created Islam !!!

Jews are first to populate Madinah… yeah sure not Alamaaliq
