Arent they descended from Ishmael? That would explain it.
Many “modern” folk scoff at the Bible (Torah) but in it, it states,
Genesis 16:12 ESV / 57 helpful votes
He shall be a wild donkey of a man, his hand against everyone and everyone’s hand against him, and he shall dwell over against all his kinsmen.
Now whether you believe or not, this DOES INDEED appear to be the case with what we actually see in the world. It’s our choice to believe in this or call it nonsense but, look all around us in our modern epoch...look at Islam.
