Didn’t Mad Mo kill a bunch of Jews not too long before he passed (pork be upon him)?
Here is some elaboration:

Yes as I remember reading my history of it, Mad Mo presented himself as a prophet of God in the tradition of the past Torah\Old Testament prophets to Jewish tribes ( I think there was more the one!) in what is today Northern Saudi Arabia. They refused to accept him in fact laughed at him. He rewarded them with a massacre, killed all the males, sold the women and children into slavery. Or so the story goes, if you’re convinced Mad Mo actually existed, or existed in the form their tradition demands and is commonly accepted.
