Is Jewish -Islamic system intermingling allowed in Judaism?

Question

This well known and well learned rabbi on his popular facebook page promotes intermingling and cross mixing of Jewish and Islamic ideas and believes that Islam is a welcome reformation of rabbinical Judaism. He has also has many articles there showing commonality between both Judaism and Islam. Hence is it allowed for rabbis and general population to practice both Islam and Judaism simultaneously like how this rabbi seems to be doing. Also even his Jewish followers consider him well learned rabbi, So the question is does Judaism permit practicing all Islamic activities? and can Islam be welcomed as a reformation in Judaism?

He writes on linkedin page:

Before the religious courts, I propose that Muslims are derived from the God-fearers mentioned in the Torah. To do this, I argue historically, that the people referred to as Muslims (before the Qur'an came) are identical with the God-fearers mentioned in the Torah and related works.

Note: There might be other rabbis supporting Judeo-Christian intermingling like Jews for Jesus, but here the case is different as Islam is not avodah zarah and conversion to it does not demand death .

Answer 1

There has certainly been some cross-pollination of ideas over the years, e.g. certain moral lessons that you'd see in the classical Jewish philosophical work Hovot HaLevavot also appear in the Hadith. And as Islam is clearly a monotheistic faith, it avoids the problems posed by laws about "idols" or "pagans." (E.g. halacha has a lot of problems with a Jew entering a pagan temple, but not a mosque.) Maimonides wrote (just before the year 1200) that Islam spread the language of prophetic monotheism to many peoples that Judaism didn't reach. He also wished that Jews would show the same decorum in their synagogues that Muslims do in their mosques.

However, good fences make good neighbors, too. Islam and Judaism are two different faiths, and we honor neither of them by confusing that line. Judaism did not and can not accept that its tradition of laws were -- abrogated, deprecated, reinterpreted, whatever you want to call it -- by Mohammad. Jews are allowed to drink alcohol. (Now you'll find Jewish cultures that drink more, and some that drink less, and many Jews may even find the Islamic practice of abstinence to be laudable, but Judaism never did and never will ban alcohol entirely.) Muslims are monotheists but not Jews, and thus Jews are not allowed to marry them. And if a Jewish man married a Muslim woman, neither faith would consider the child to be legally one of their own. (Halacha defines Jewish status as matrilineal; sharia defines Islamic status as patrilineal.)

I've never heard of the rabbi you're quoting, and I really don't care. It's the same now as it was when Maimonides wrote extensively about this 800 years ago. They are two different faiths.
