"Going to (the) mosque" is only one of many times when Muslims might have to struggle with how to express something in English. I don't have all the answers. I guess no one does.
I couldn't agree with you more, Okaasan. This is exactly the same problem we have in Iran. Here we have two university courses named "A Survey of Translated Islamic Texts." The translations are indeed far from the original texts in every sense, and it seems no one can come up with better translations, as many Islamic concepts just do not exist in English. Sometimes, the translations sound even funny!
