Some scholars suspect that the prologue to the Kutadgu Bilig, which is much more overtly Islamic than the rest of the text, was not written by Y?suf, particularly the first prologue, which is in prose, unlike the rest of the text. Yusuf Has Hajib died in 1085 at the age of 66 in uyghur city Kashgar, and was buried there. There is now a mausoleum erected on his gravesite . He is remembered as a prominent Uyghur scholar
