As the propagation of non-Islamic faiths is forbidden under Islamic law, missionary work is banned. But that won't stop the mullahs from being paranoid about it, and taking the opportunity to remind the unbelievers of their place in the Islamic Republic of Iran. "Iran Seizes 6,500 Bibles to Stop 'Deceiving' Christian Missionaries," by Fionna Agomuoh for the Christian Post, August 17:
Iran has seized 6,500 copies of the Bible in northwest Iran in what appears to be the latest crackdown by Iranian authorities against Christianity in the country.
Few details are known about the seizure, however, Christian news agency, Mohabat News, reports that Dr. Majid Abhari, adviser to the social issues committee of the parliament in Iran stated, "These missionaries with reliance on huge money and propaganda are trying to deviate our youth."
In a government interview with Mehr news agency, Abhari explained that the Bibles were taken because of governmental concerns that Christian missionaries mean to "deceive" young Iranians with "false propaganda."
"The important point in this issue that should be considered by intelligence, judicial and religious agencies is that all religions are strengthening their power to confront Islam, otherwise what does this huge number of Bibles mean?" he told Mehr.
According to persecution advocacy group, Voice of the Martyrs, missionary work is banned in Iran, though Christian conversion has been growing in the majority Islamic country in recent years.
Conversion from Islam to another religion, known as apostasy, is also a crime in Iran, and offenders are often arrested and tried in court. Recent legislation is aiming to have the crime of apostasy punishable by death.
The death penalty for apostasy comes from Muhammad's own orders, and has clearly survived in Shi'ite as well as Sunni traditions...
