Around five in the morning one day in the summer of 2007, just as Imam Khalid Latif was preparing for the salatul-fajr, the obligatory prayer between dawn and sunrise, the phone in his small Manhattan apartment began to ring.
He had been up late the night before, having just conducted a nikkah, a Muslim wedding ceremony, for a South Asian couple he knew from New York University, where he served as chaplain. Afterward, he offered to drive a few students back into the city, so he had not gotten home as early as he might have expected.
On the phone was an operations dispatcher from the New York Police Department (NYPD), where Imam Latif also served as a chaplain, having been named only three months earlier to the post. This was his first emergency call: Two cops had been shot, one fatally. He was to go to the hospital to minister to the families and fellow officers of the fallen.
