The Islamic origin story is based on a false perversion of the time Abraham took his only son Isaac (the son God told him and Sarai they’d have) up to be offered. Islam says it was actually his illegitimate son Ishmael (the son Sarai convinced Abram to have with their slave because she thought she was too old). God was not happy about their decision to doubt Him and try to take matters into their own hands, but He did promise a great (size not morally) nation to Abram’s seed, so He kept His word, and that’s what became Islam. God warned he’d be a “wild man” and make war with everyone. It was, is, and always will be a curse and reminder of what comes from deciding for yourself what you think God must’ve meant, instead of just trusting Him. But God made it clear that Abraham (name changed after Isaac was conceived) only had one son. The son of Hagar the bondwoman was evil and cursed, as were his 12 sons, and everything that’s come from those generations would be too. So they might have heard and passed on a lot of the semi-regional history, but their accounts are untrustworthy as far as details are concerned. There’s also a very interesting thread with the concept of being a wild man, wilderness man, great hunter etc. as it paints a picture of being away from the tent/tabernacle, which was the place God resided in those days. It was a way of saying they were far away from God. It is also attributed to Nimrod and Esau, among others. It’s a cool side narrative that better explains why certain things went down the way they did, when you understand who was wicked
