Local and international media groups have condemned the verdict against Sayed Perwiz Kambakhsh, which family members say followed a "secret trial" at which Kambakhsh had no legal counsel.
The Institute for War and Peace Reporting (IWPR), a nongovernmental group that helps train journalists in troubled spots, has meanwhile accused the authorities of prosecuting Kambakhsh in order to punish his brother, a contributor to IWPR publications.
Family members denounced the verdict, saying the January 22 trial in Mazar-e Sharif was held behind closed doors and they did not even know the hearing had been scheduled.
Kambakhsh's brother, Sayed Yaqub Ibrahimi, tells RFE/RL's Radio Free Afghanistan that the verdict was "unjust" and his brother did not have a lawyer defending him at the hearing.
"I told [my brother], 'Don't worry about this. It is not the final decision of the Afghan courts,'" Ibrahimi says. "But, anyway, every member of our family is concerned about it. We are sorry to see this unjust decision by the Balkh court."
Sayed Perwiz Kambakhsh, a journalism student at Balk University who also worked for the newspaper "Jahan-e Naw" (The New World), was arrested in late October over a controversial article that commented on verses in the Koran that were about women.
Kambakhsh's brother and other sources said the article had in fact been taken off the Internet and Kambakhsh had simply distributed copies of it among fellow university students.
"We feel very strongly that this is a complete fabrication on the part of the authorities up in Mazar, designed to put pressure on Parwez's brother Yaqub, who has done some of the hardest-hitting pieces outlining abuses by some very powerful commanders in Balkh and the other northern provinces," IWPR country manager Jean MacKenzie says.
MacKenzie notes that authorities in Balkh had searched Ibrahimi's computer and taken contact details of sources, adding that "we feel that what is happening with Parwez is not a very veiled threat against Yaqub Ibrahimi."
Reporters Without Borders, a Paris-based media watchdog, says it was "shocked" at the verdict against Kambakhsh and has urged Afghan President Hamid Karzai to intervene.
Afghan media outlets have sprung up in large numbers since the ouster of the hard-line Taliban regime in late 2001, although press freedoms frequently run up against official obstacles or opposition from conservative forces that include the clergy.
Legal Questions
A three-judge panel concluded on January 22 that the article in question violated the tenets of Islam.
Rahimullah Samandar, who heads Afghanistan's Independent Journalist Association, strongly condemned the verdict against Kambakhsh. He tells Radio Free Afghanistan that the ruling contravenes the country's 2004 constitution.
"The Afghan Independent Journalists Association, and the...the Committee to Protect Afghan Journalists..., both organizations, strongly condemn this decree," Samandar says. "This is illegal, this is unjust, it's unfair. It is in accordance with neither Afghan law nor the Afghan Constitution."
