The holy month of Ramadan began on Tuesday. Ramadan is a time for reflection and spiritual growth, and thousands of Texas Muslims will take part by fasting in the during the day, breaking that fast and praying in the evening. Muslims are a fast-growing community in the state; there are at least 420,000 Muslims in Texas today. But Austin-based Imam Islam Mossaad says the community was much smaller when he was growing up in Austin in the late 1970s and ’80s. Mossaad was born in the United States to Egyptian parents who came to the here so his father could pursue his Ph.D. in electrical engineering at the University of Texas at Austin. Back then, the city only had one mosque, started by Muslim UT graduate students who worshiped in a house they had converted. Now the city has 10 mosques, and Mossaad’s congregation, the North Austin Muslim Community Center, has about 2,000 worshipers for Friday prayers.
