It’s not every day that a fellow who runs a $250 million financial services firm has a fatwa, or Islamic religious ruling, issued against him. But that’s what happened four years ago when my then $7.3 million company, SKS Microfinance, started doing business in Nizamabad, India. Armed with broken bottles and machetes, a gang of local thugs intimidated, attacked, and stole cash from some of our loan officers. They tried to extort money from us in exchange for permitting SKS to operate safely in the region. When we refused to pay, they spread rumors that we were trying to convert people to Christianity. The fatwa, handed down by local clerics, said it was a sin to borrow from us.
