According to numerous Arab websites (including UPI Arabic), the Saudi Ministry of Islamic Affairs sent out an alert to mosque imams not to pray for the destruction of Jews and Christians in their Friday sermons, noting that the "correct" prayers should be against "aggressors" only.
Apparently, religious incitement in Saudi mosques is so widespread that even the government has to get involved to tone it down.
And these are the "moderates."
UPDATE: New reports are saying that the Saudi ministry has denied sending out such an alert.
I couldn't find any such mention on the Ministry's website.
