The group is posting advertisements on the outside of Muni buses. They include phrases like "you deserve to know" and "why Islam," along with a phone number for more information.
Their goal is to urge more non-Muslims to learn about Islam and help remove negative stereotypes.
"We're basically sick and tired of people labeling us, of defining us, framing us, so I think it's time for us to stand up and basically inform the American public of who we are and what is our true identity," said Muhammad Hanif with the Islamic Circle of the Bay Area.
The ads will appear on about 170 Muni buses and 10 cable cars.
