It is not a Muslim ban but Jews who are born in the seven banned countries are excluded

"The U.S. embassy in Tel Aviv issued a statement on Tuesday to clarify the status of visas held by Israelis born in Arab countries, in light of an entry ban issued by the Trump administration to nationals from seven Muslim-majority countries.  The embassy said that: “If you have a currently valid U.S. visa in your Israeli passport and were born in Iraq, Iran, Libya, Somalia, Sudan, Syria, or Yemen, and do not have a valid passport from one of these countries, your visa was not cancelled and remains valid."
