《新唐书·列传·卷一百四十》
皇帝说： 突厥盛夏而飞霜，五个太阳同出，三个月亮并明，瘴气满野。他们见如此灾异还不修德，是不怕天；他们迁徙无定规，六畜多死，是不用地；其俗人死火焚，现人死均墓葬，违背祖宗的传统，是侮鬼神；与突利不睦，互相攻杀，是与亲不和。
帝曰： 突厥盛夏而霜，五日并出，三月连明，赤气满野，彼见灾而不务德，不畏天也。迁徙无常，六畜多死，不用地也。俗死则焚，今葬皆起墓，背父祖命，谩鬼神也。与突利不睦，内相攻残，不和于亲也。
The Emperor said: The Turks had snow falling in the middle of summer, five suns appearing at the same time, three moons shining together, and miasma filled the fields. They saw such disasters but still did not cultivate virtue, so they are not afraid of heaven; they migrated without any definite rules, and many of their livestock died, so they did not use the land; their custom was to burn the dead, but now they buried the dead, violating the traditions of their ancestors, which was an insult to ghosts and gods; they were not on good terms with Tulish and killed each other, which was incompatible with their relatives.
