Circumcision in Islam is close to universal in practice and rests on a different legal footing from the Jewish rite.
It is not commanded in the Quran. It is derived from prophetic tradition and from the practice of Abraham, and jurists divide over whether it is obligatory or strongly recommended, with the Shafii school treating it as required and others as recommended custom. The timing is correspondingly loose: infancy, early childhood, or the approach of puberty, depending on region. In many countries it is a public celebration with the boy dressed for the occasion, a large gathering and gifts, and Turkey, Egypt, Indonesia, Pakistan and the Gulf states keep the practice with quite different ceremonial around it.
Christianity decided against it early and explicitly. The dispute recorded in Acts and in Paul's letters is the first great argument in the church, and it settled that gentile converts need not be circumcised. That decision is what made Christianity separable from Judaism, and it is difficult to overstate its consequences. Two groups of churches are exceptions for cultural rather than doctrinal reasons: the Ethiopian, Eritrean and Coptic churches practise it, as does much of Christian sub-Saharan Africa.
Beyond the Abrahamic traditions the practice is widespread and independent. It is attested in ancient Egypt in tomb reliefs and in preserved bodies. It is a standard element of male initiation across large parts of Africa, Aboriginal Australia and Melanesia, where it is typically performed at adolescence within a longer period of seclusion and instruction, is bound up with age-grades and adult status, and has nothing to do with covenant in the Abrahamic sense. Reading those practices through a Jewish or Muslim frame, as early ethnographers routinely did, produces a false parallel from a real physical resemblance.
