It's believed the three-aisle bodega laundered money for the terrorist organization Sunni Sipah-e-Sahaba/Pakistan (SSP).
Muawia was allegedly a favored assassin with the SSP, which has been blamed for the massacres of scores of Pakistani civilians as it pushed a pro-Sunni, anti-American agenda.
An SSP cell was first discovered in New York City in 2003, when investigators raided a Brooklyn apartment and found recruitment documents and membership forms, sources said.
Another SSP member was deported after being caught in 2004 photographing the Brooklyn and Williamsburg bridges.
