There was an interesting post on alt.folklore.urban discussing several examples of Muslim hoaxes alleging there have been people who were recently cursed by Allah, for one reason or another, and transformed into bizarre animals.
For instance, Arabic newspapers ran one story about a girl who threw the Quran at her mother and was transformed into a large, rat-like creature. (The story became a popular video as well.) An image (below) accompanied the story, showing what the girl had become.
In reality, the image of the rat-like creature was lifted from an art exhibit titled "Leather Landscape" by Patricia Piccinini. Piccinini posted a statement online disavowing any knowledge of how the 'cursed' story originated and expressing sympathy for anyone disturbed by it.

A second story circulating in Arabic-language communities (via a youtube video) details the case of a girl who kicked the Quran and was transformed into an ugly mermaid-like creature. In reality, the creature shown is a guitar fish.
If the punishment for kicking or throwing the Quran is to be transformed into an animal, then what's the punishment for making bizarre stuff up to scare people?
