An Indonesian man was condemned on Thursday to 30 month in prison for posting "God doesn't exist" on his Facebook page and sharing inappropriate content about the Prophet Mohammed online, Hurrieyt Daily News has reported.

The 30-year-old was charged with "deliberately spreading information inciting religious hatred and animosity".

Alexander Aan was sentenced for creating a Facebook group on which he shared comic strips of the prophet having sex with his servant and publishing three articles about the prophet, including one of them describing the prophet being attracted to his daughter-in-law.

The suspect was condemned under the Electronic Information and Transactions law resulting in a 30-month sentence.

"What he did has caused anxiety to the community and tarnished Islam," presiding judge Eka Prasetya Budi Dharma told the Muaro Sijunjung district court in western Sumatra.

Aan avoided a three-and-a-half-year prison sentence after prosecutors dropped two other charges which included “persuading others to embrace atheism and blasphemy.”

On January 18, a number of local residents assaulted Alexander Aan after he posted the material online and declared himself an atheist.

The Indonesian constitution provides for freedom of religion, but the Government recognizes only six major religions.
