Among these writers was Pîr Xidir and Khalil Jindy, who together in 1979 published the book "Êzdiyati" (In Light of the Scripts of Êzidîsm) which was printed by the Kurdish Scientific Academy.
On a cold winter day of that year, at the beginning of an Islamic Education lesson, the teacher entered the class and ordered all students who had no religion to go out.
