Tom C submitted this link describing the content of salat, the prayers Muslims are required to say five or 10 times per day — the number depends on the sect. The prayers include implicit statements that the Jews are cursed and the Christians have gone astray.

It’s kind of Pharisaical, actually.
Compare it to the Our Father.
