The mufti presides over his father-in-law 's mosque and madrassa , Jamiat-Qurania-Arabia , in Dhaka , where the traffic caused by 600,000 bicycle rickshaws , more than in any other city in the world , is so intense that it can take hours to travel fewer than 10 miles from Louis Kahn 's ethereal Parliament -- a relic of a more hopeful period in Bangladesh 's democracy -- to the warren of lanes in the old part of town where the mufti is based .
