Why should he command or request any religious activity in his role as President?
I don't want a Buddhist or Muslim president telling me to pray or meditate or go on jihad. Do you need the most visible official of the state giving you religious instructions? I don't.
Interestng, isn't it that a word like "Muezzin" would be used, which from a search on-line means someone who offers an islamic prayer. (I love it when I learn a new word!)
presbyrev, President Bush did not order you to pray, he did not tell you when to pray, he asked for you to pray. If you don't want to, don't. If you do, pray.
