Comedy Central bleeped out all references to the Prophet Muhammad in Wednesday night's episode of the animated show "South Park."
The episode was a continuation of last week's episode which depicted the Prophet Muhammad in a bear suit.
A radical Muslim website threatened the show's creators following that episode.
Comedy Central confirmed to FoxNews.com that it had censored the show, and that the episode was not available on its website.
In addition to bleeping the words "Prophet Muhammad," the show also covered the character with a large block labeled "Censored."
A radical Islamic website had warned the creators of "South Park" that they could face violent retribution for their depiction of Prophet Muhammad.
RevolutionMuslim.com posted the warning following the 200th episode of Trey Parker and Matt Stone's "South Park," which included a caricature of the Prophet Muhammad disguised in a bear suit. The web posting also included a graphic photo of Theo van Gogh, a Dutch filmmaker who was murdered in 2004 after making a documentary on violence against Muslim women.
"We have to warn Matt and Trey that what they are doing is stupid and they will probably wind up like Theo Van Gogh for airing this show," the posting reads. "This is not a threat, but a warning of the reality of what will likely happen to them."
Abu Talhah al Amrikee, the author of the post, told Foxnews.com he wrote the entry to "raise awareness." He said the grisly photograph of van Gogh was meant to "explain the severity" of what Parker and Stone did by mocking Muhammad.
"It's not a threat, but it really is a likely outcome," al Amrikee said, referring to the possibility that Parker and Stone could be murdered for mocking Muhammad. "They're going to be basically on a list in the back of the minds of a large number of Muslims. It's just the reality."
Al Amrikee said the website is considering a protest against the "disgusting" show, which also depicted the Prophet Muhammad in an episode on July 4, 2001.
"This is not a small thing," he said. "We should do whatever we can to make sure it does not happen again."
The posting on RevolutionMuslim.com also includes audio of a sermon by Anwar al-Awlaki -- a radical U.S.-born preacher now believed to be hiding in Yemen -- who discusses assassinating individuals who defame the Prophet Muhammad. It also included a link to a 2009 story in the Huffington Post that gave details of Stone and Parker's mansion in Colorado.
A Comedy Central rep told FoxNews.com that the network has no comment on the posting.
