According to the transcript from the Balkh court proceedings, the prosecutor said Kambakhsh admitted to writing three paragraphs of the article and had initialed them.
He also was accused of writing, "This is the real face of Islam ... The prophet Mohammad wrote verses of the holy Quran just for his own benefit."
Prosecutor Ahmad Khan Ayar told the appeals court that the primary court sentence was "the right decision" according to Islamic law and the Afghan Constitution.
"Kambakhsh has insulted Islam by writing these paragraphs, and he has insulted the Prophet Muhammad," Ayar said. "I ask the appeals court today to uphold the decision of the primary court of Balkh and sentence him to death."
A number of rights groups have demanded that the case be annulled and Kambakhsh set free. A U.S. State Department spokesman expressed concern that Kambakhsh was sentenced to death for "basically practicing his profession."
The New York-based Committee to Protect Journalists said it was concerned that Kambakhsh may have been targeted because his brother, Yaqub Ibrahimi, had written about human rights violations and local politics.
Ibrahimi said the family approached more than 10 lawyers who were initially willing to take the case but later changed their minds.
A week after Kambakhsh was sentenced, lawmakers in the upper house of Parliament lauded the verdict. Conservative clerics and tribal elders have demanded that the government support the court's decision.
More than 150 people -including several Western observers and more than 20 journalists -filled the courtroom Sunday to view the proceedings.
Kambakhsh said he did not believe he needed a defense lawyer at the appeals level because he had not done anything wrong, but pressed further said he would like to have one.
