(Beirut) – Saudi Arabia’s school religious studies curriculum contains hateful and incendiary language toward religions and Islamic traditions that do not adhere to its interpretation of Sunni Islam, Human Rights Watch said today. The texts disparage Sufi and Shia religious practices and label Jews and Christians “unbelievers” with whom Muslims should not associate.

A comprehensive Human Rights Watch review of the Education Ministry-produced school religion books for the 2016-17 school year found that some of the content that first provoked widespread controversy for violent and intolerant teachings in the aftermath of the September 11, 2001 attacks remains in the texts today, despite Saudi officials’ promises to eliminate the intolerant language.

“As early as first grade, students in Saudi schools are being taught hatred toward all those perceived to be of a different faith or school of thought,” said Sarah Leah Whitson, Middle East director at Human Rights Watch. “The lessons in hate are reinforced with each following year.”

This research was part of a broader investigation into Saudi officials and religious clerics’ use of hate speech and incitement to violence for an upcoming Human Rights Watch report. The reviewed curriculum, entitled al-tawhid, or “Monotheism,” consisted of 45 textbooks and student workbooks for the primary, middle, and secondary education levels. Human Rights Watch did not review additional religion texts dealing with Islamic law, Islamic culture, Islamic commentary, or Qur’an recitation.
