Is this any big surprise?
However polygamy is allowed in both Judaism & Islam.
Don't bring up Rabbeinu Gershom because his ban was only for 1000 years which is way over.
Only reason we don't do it is beacuse it is against the law of the land.
But if for instance the US or Israel or any place else legalizes polygamy then multiple wives would be allowed under Jewish law.
Having said that Elijah Muhamad was a POS Jew-hater & hated all whites.
