"The #hamsa itself is not a uniquely #Jewish symbol. It’s used by people of all religions with roots across the #MiddleEast and the #Levant. Some call it the hand of #Fatima (#Mohammad’s daughter), some the hand of #Miriam (after #Moses’ sister). Five is an auspicious number in both #Islam (the five pillars of Islam) and #Judaism (the five books of the #Torah). The symbol’s roots might be in early #Pagan traditions that pre-date monotheistic religions, but it has become a popular symbol in both #Judaism — #Jews are speculated by scholars to be the first to use it as an amulet — and #Islam. Many Jews wear hamsa jewelry and put hamsa amulets around their homes."
