According to Article (273) of the Jordanian Penal Code No. 16 of 1960 that the West Bank uses as the basis for its laws, this offense is punishable for 1 to 3 years in prison.
The entire code is interesting - it is the same one that is lenient for honor killings that was supposedly modified by Abbas.
Other laws:
- Breaking the fast during Ramadan - up to one month in prison.
- Desecrating or destroying any place of worship with intent to insult that religious group (not only Islamic) - between one month and two years in prison.
- Publishing something that insults religion - up to three months in prison.
- Publicly insulting religion in speech - 1-6 months in prison.
Any lawyers want to go after the many insults to Judaism and Christianity we've seen there over the years?
(CORRECTION: I originally made a mistake and reported this as happening in Gaza. h/t StamEhad.)
