رباعيات الخيام
In the late 1960s and early 1970s, Shah came under attack over a controversy surrounding the [[Rubaiyat of Omar Khayyam#Robert Graves and Omar Ali-Shah|1967 publication of a new translation]] of [[Rubaiyat of Omar Khayyam|Omar Khayyam's Rubaiyat]], by Robert Graves and Shah's older brother, [[Omar Ali-Shah]]. The translation, which presented the Rubaiyat as a Sufi poem, was based on an annotated "[[Crib sheet|crib]]", supposedly derived from a manuscript that had been in the Shah family's possession for 800 years. L. P. Elwell-Sutton, an orientalist at [[Edinburgh University]], and others who reviewed the book expressed their conviction that the story of the ancient manuscript was false.
