Islam (Arabic: الإسلام) is a monotheistic religion that arose in the 7th century based on the religious teachings of Muhammad.
Islamteaches that God may reveal His will to mankind though an angel; such recipients of revelation are known as prophets.
Islamic teaching holds that life is given by Allah and should not be taken lightly, but it allows severe punishment, up to and including capital punishment, for certain kinds of crime; these include, in strict interpretations, all extramarital sexual relations (zina') by both men and women—though only married adulterers may be punished with death.
