7. Jews and Muslims both require male circumcision
In the Bible, Abraham was commanded by God to undergo circumcision, as a sign of the divine covenant established between them. This requirement was subsequently inherited by all of Abraham’s male descendants; accordingly, it has since remained an established practice throughout the long history of Judaism.
According to the Torah (the first section of the Hebrew Bible), male Jewish newborns are to be circumcised on the eighth day after their birth. This occasion is commonly known as a bris (short for “covenant of circumcision”), and has the status of a religious ceremony. The actual procedure is performed by a trained Jewish specialist known as a mohel (“circumciser”), and a celebratory meal follows the ritual.
