Zalmai lost friends quickly. He was condemned by colleagues and even by others involved in the book's printing. A mob stoned his house one night, said his brother, Mahmood Ghaws.
Police arrested Zalmai as he was fleeing to Pakistan, along with three other men the government says were trying to help him escape. The publisher and the mosque's cleric, who signed a letter endorsing the book, were also jailed.
There is no law in Afghanistan prohibiting the translation of the Quran. But Zalmai is accused of violating Islamic Shariah law by modifying the Quran. The courts in Afghanistan, an Islamic state, are empowered to apply Shariah law when there are no applicable existing statutes.
And Afghanistan's court system appears to be stacked against those accused of religious crimes. Judges don't want to seem soft on potential heretics and lawyers don't want to be seen defending them, said Afzal Shurmach Nooristani, whose Afghan Legal Aid group is defending Zalmai.
The prosecutor wants the death penalty for Zalmai and the cleric, who have now spent more than a year in prison.
Sentences on religious infractions can be harsh. In January 2008, a court sentenced a journalism student to death for blasphemy for asking questions about women's rights under Islam. An appeals court reduced the sentence to 20 years in prison. His lawyers appealed again and the case is pending.
In 2006, an Afghan man was sentenced to death for converting to Christianity. He was later ruled insane and was given asylum in Italy. Islamic leaders and the parliament accused President Hamid Karzai of being a puppet for the West for letting him live.
Nooristani, who is also defending the journalism student, said he and his colleagues have received death threats.
"The mullahs in the mosques have said whoever defends an infidel is an infidel," Nooristani said.
The legal aid organization, which usually represents impoverished defendants, is defending Zalmai because no one else would take the case.
