Circumcision

Circumcision is the removal of the foreskin from the human penis. In the most common procedure, the foreskin is opened, adhesions are removed, and the foreskin is separated from the glans. According to some hadiths, Muhammad was born without a foreskin (aposthetic), while others maintain that his grandfather, Abd al-Muttalib, circumcised him when he was seven days old. Many of his early disciples were circumcised to symbolize their inclusion within the emerging Islamic community.[citation needed] Some hadiths report that Heraclius, Emperor of the Byzantine Empire, had referred to Muhammad as "the king of the circumcised".
