I read the first issue of 52, and I think there was a Muslim. I know little about the DC Universe, so I don't know who the superpowered guy was--I think he was a Middle Easterner--but he saw a Muslim suicide bomber in a crowd of people, so he pulled him up into the air by one arm (which ripped his arm off) and threw him high enough to explode away from the crowd. That was kind of cool. I think maybe you're referring to this guy, directly below... yes?

If so: that's Black Adam, a sort of muddled hero/villain-type character; Egyptian, not Muslim. :)
