At a traffic circle in Maryland, Mona Eldadah watched her father plodding in circles.
Hadi Rahnama, 77, was walking around a black cube, a replica of the Kaaba shrine in Mecca, to demonstrate the tawaf, or ritual prayer, that Muslims perform when they visit the shrine on the hajj.
Eldadah corrected her father.
"No, Daddy, the idea is that the car is actually going to do the tawaf," she said. "It's a drive-through."
