Context: I am a 44-year-old woman condemned to 22 years in prison by the Islamic Republic of Iran and I know very well that this is not the end of the story, I have no doubt that those who provided the ink for penning such rulings and those who used it to write them, as well as the noble people of my country, all know I have committed no crime or sin to deserve such a harsh punishment. I have faith in the path I have chosen, the actions I have taken, as well as my beliefs. I am determined to make human rights a reality [in Iran] and have no regrets. If those who claim to be spreading justice are firm on their judgment against me, I am also firm on my faith and beliefs. I will not waiver under tyrannical punishments that will limit my freedom to the four walls of the prison cell. I will endure this incarceration, but I will never accept it as lawful, human or moral, and I will always speak out against this injustice.
