Several Massachusetts parents are reportedly outraged over a textbook that includes a verse about the teachings of Islam, and they have announced they don't want their children learning about the religion.

One parent, Anthony Giannino, even pulled his child out of the Revere Public School system when he learned his son was using a textbook that reads "I bear witness that there is no God but Allah" in a section that describes a Muslim prayer, accordig to WHDH.

"No religion should be taught at school. In their paper it says Allah is their only God. That's insulting to me as a Christian who believes in Jesus only," Giannino told WHDH.

Other excerpts describe the life of the Prophet Muhammad, who founded the religion and spread the word of Allah centuries ago.

"We don't believe in Allah. I don't believe in my son learning about this here," Giannino told the station. "If my son was from another country and came here, he would have been catered to. But where he's not being catered to, they give him an F."

Revere Public Schools sent parents a letter saying the section of the textbook, the name of which was not mentioned, is just part of the district's curriculum.

"No religion is taught with the purpose of converting students to that religion," reads the letter obtained by the station.

Some parents, however, don't see anything wrong with what the textbook says.

"What is Muslim about, what is Christianity about. That's what I teach at home," Idalia Garcia told the station. "Everybody should respect everybody else's religion."

Giannino, who believes the district should have warned parents about the lessons on Islam, has started a petition against the curriculum.
