Brooklyn —

Abdulrauf Khan, 40, warns a group of volunteers to avoid stepping on errant nails in the kitchen of a small home on Brighton 8 Street in Brighton Beach. He’s surrounded by ripped up floorboards and industrial trash bags full of debris. His black felt hat is speckled with white dust.

During Hurricane Sandy, the basement and first floor of this home filled with water. Now the house is being gutted while the residents, a family of five, are in a shelter.

Khan is the assistant director of disaster relief for the Islamic Circle of North America Relief USA, a nonprofit relief and social services organization with headquarters in Jamaica, Queens. The responsibility to help those in need is informed by the Islamic faith, Khan says.
