The parents were not planning to swim, only to supervise their children, the lawsuit said. They had previously been admitted when not wearing swimsuits. "A week later, I sent my sister to go to the water park," Yaqub told WLS-TV, Chicago. "My sister doesn't wear the Muslim veil on her head. She went in a running suit, or pajama. She wasn't wearing swimming trunks. The same lady that denied us entry let my sister in with no problem."

A Brookfield man filed two lawsuits against the Forest Preserve District of Cook County alleging that his wife was denied access to the Cermak Family Aquatic Center because she was wearing traditional Muslim dress. Mahmoud Yaqub went to the aquatic center, which has a wading area, fountains and sprinklers, with his wife and two children.
