"He will be a wild donkey of a man, and his hand will be against everyone, and everyone’s hand against him; he will live in hostility toward all his brothers".

Genesis 16:12

This prophecy was given by the angel of the Lord to Hagar concerning her son Ishmael, (the arabs) describing his future character and the nature of his relationships.

Just a weird Bible coincidence

There’s an old Muslim proverb that describes this in detail.

Me against my brother. My brother and I against our cousins. My cousins against our clan. Our clan against other clans. Our clans against the world.
