The Hurva is not the only synagogue being redidicated this month. According to the New York Times, the Rambam Synagogue (aka "Rav Moshe") in Cairo is being rededicated next week.
The synagogue is said to have healing powers:
But this was not just any synagogue. Rav Moshe was considered to have special healing powers. One elderly Egyptian Jew now living in Europe told me how his childhood stuttering disappeared after his mother made him spend the night there. His miracle cure was a commonplace experience for many of Cairo’s Jews who sometimes called it the “Jewish Lourdes.”
Not only Jews came to Rav Moshe. King Fuad, who ruled Egypt from 1917-1936, found relief for his ailments after spending a night at the synagogue, although the plaque attesting to his visit has long since disappeared.
I wonder what the Rambam himself would think of this. I wouldn't imagine he'd be too impressed with these healing powers. Or would he?
