While Rabbi Moshe Feinstein permitted, in principle, entry to some parts of the site, most other Haredi rabbis are of the opinion that the Mount is off limits to Jews and non-Jews alike. Their opinions against entering the Temple Mount are based on the current political climate surrounding the Mount, along with the potential danger of entering the hallowed area of the Temple courtyard and the impossibility of fulfilling the ritual requirement of cleansing oneself with the ashes of a red heifer. The boundaries of the areas which are completely forbidden, while having large portions in common, are delineated differently by various rabbinic authorities.
