I assume, from the ignorance of your statement, that you have never been to Jerusalem. Arabs do pray wherever and whenever they wish, as the air rings with the calls to prayer from the minarets five times a day. Muslims are not barred from the Kotel and if they pray there, that is their business. When Jews are allowed on the Temple Mount, they cannot bring prayer books, wear tallits, or even move their lips. Police arrest Jews who they think are praying. I realize that going to Israel might destroy your position of speaking from total ignorance, but it might be worth the trip. British Airways still goes there, I believe.
