Before I submitted myself to Allah (swt), I visited a Masjid in my area on a Friday. Honestly, I have never felt more welcome anywhere in my life. I went with a small group of Muslim friends who introduced me to the Imam. The Imam didn't speak English, but there were several brothers eager to translate. I wasn't planning on participating in Jum'ah prayer, because I thought it would be inappropriate for a non-Muslim to do so, but the brothers welcomed me to join them. They showed me how to make Wudu and told me that it was okay if I didn't know what to say during prayer; I could just think of Allah (swt) and that was enough. Hearing the sermon (khutbah?) and participating in the prayer was a powerful experience. I would be lying if I said that I wasn't at the brink of tears at one point. Afterwards, they invited me to have lunch with them, and by the time I left every brother there had introduced himself and shook my hand. Overall, a wonderful experience.
If you're still thinking about visiting your local Masjid, my advice is: DO IT!
You won't regret it.
