One example does not make a case. While death for homosexuality may not be explicitly written in the Koran, harsh penalties and condemnation are a part of many hadiths. I’m not an expert on hadiths, but these days examples are only a few keystrokes away. Like I’ve said before check the testimonies of people who grew up in the faith and tell me gays don’t fear for their lives, extra-judicially if not legally.There's no death penalty for homosexuality in Islam. The bunch they hanged in Iran had raped little boys.
