The open house was hosted by the Islamic Society of East Bay to commemorate "World Interfaith Harmony Week." The event promotes harmony between all people regardless of faith.
One mosque member admits there are still lots of questions about what Muslims believe.
"We, we think that this is very, very important, especially after the unfortunate event of 9/11," said Ahsan Baig, chair of the mosque's outreach committee. "And I think Muslims have not done a lot of outreach to explain what Muslims are all about, what our faith is all about."
World Interfaith Harmony Week began through a proclamation issued by the United Nations General Assembly in 2010.
