Shomer Emunim (Hebrew: שומרי אמונים, meaning "Guardian of the Faith") is a devout, insular Hasidic group based in Jerusalem.
The Shomrei Emunim are characterized by fervent and visibly emotional prayer, and by a rigid lifestyle controlled largely by "takanos", decrees written by the Rebbe.
Rabbi Aharon worried that it would be safest not to wear wool at all, in order to avoid the possibility of violating the law altogether.
They owe their strong opinions on Zionism to the literal reading of the Talmud's proclamation that Jews should not take over the Holy Land prior to the coming of the Messiah.
Approximately ten years after becoming Shomrei Emunim Rebbe, Rabbi Aharon's son also opened a second shul in Bnei Brak, and today, he divides his time between Jerusalem and Bnei Brak, as well as occasional visits to his shul in Ashdod (headed by the Rebbe's son Rabbi Aharon Roth, the Shomrei Emunim Rov) and to Tifrach.
