Islam began as a 7th century Noahite reform among the [[Elagabalites]] and other people of the Middle East. However [[Hagarim]] of that time soon rose up to suppress their [[Idumean]] and other Karaite Judaic teachers as they followed Christianity back down along the path of [[SuppressionismSupersessionism]].
There has been much less halachic literature written about Islam compared to Christianity. It has been suggested that this is due, in part, to the fact there has not been in the way of substantial polemics directed at Islam.<ref>Much of this article is based on 'Islam and the halacha'' in ''Judaism: A Quarterly Journal of Jewish Life and Thought'', 6/22/1993, Author: Shapiro, Marc B.</ref> Almost all halachic authorities follow Maimonides and rule that Islam is not idolatry. Many halachic authorities disagree with Maimonides and rule that Muslims enjoy, at least in part, the status of a ''[[Ger Toshav]]''. Although concerning both these points there are major halachic authorities with dissenting opinions. The most serious issues with Islam from a Noahide point of view is the non-acceptance of Jewish scriptures and the "[[replacement theology]]" of the Prophethood of Muhammed. The Brisker Rav said that for Muslims to be considered Noahides, they must accept the 7 mitzvos because Hashem commanded it at Sinai. Additionally, they must honor the prohibition of "shfichas domim".
