What was the penalty for Blasphemy in Iran during the Nineteen Nineties ?

Iran's law against blasphemy derives from Sharia. Blasphemers are usually charged with "spreading corruption on earth", or mofsed-e-filarz, which can also be applied to criminal or political crimes. The law against blasphemy complements laws against criticizing the Islamic regime, insulting Islam, and publishing materials that deviate from Islamic standards. The regime uses these laws to persecute religious minorities such as the Sunni, Bahai, Sufi, and Christians and to persecute dissidents and journalists. Persecuted individuals are subject to surveillance by the "religious police," harassment, prolonged detention, mistreatment, torture, and execution.
