I haven't read of condemnation from Muslim leaders regarding well-publicized reports of Ahmadinejan's rants. If anyone else has, I would appreciate links. I did read one report of an Islamic cleric supporting these pathetic comments (NY Times/Reuters). Then, there is Iran's Interior Minister stating that Ahmadinejan has been "misunderstood" (equally pathetic).
Not that I'm expecting support for Israel from Muslim leaders, whether political or religious. However, I would expect swift and stern rebuke to such blatant idiocy.
