Islam and Christianity are sometimes referred to as the 'daughter religions' of Judaism because both affirm that God did reveal His will to the Jews and many of their idea are adopted from Judaism, although the term 'daughter religions' is never found in any of the standard Jewish sources. The accepted view among the medieval thinkers is that Islam, though false from the standpoint of Judaism, is a pure monotheistic faith so that a non-Jew who is a Muslim does not offend against the Noahide laws, one of which is the prohibition of idolatry. Maimonides goes so far as to rule that if a Jew is ordered to embrace Islam or be killed, he is not obliged to suffer martrydom. Others disagree. It is true, they argue, that a convert to Islam is not an idolater but, by becoming a Muslim, he rejects the Torah and to avoid this act of apostasy, too, martrydom is demanded. " |
