The Tarikh Yamini also contains information chronicling Sultan Mahmud's expeditions as well as the end of the Samanid Empire.[3] Al-Utbi, being Mahmud's secretary, did not accompany the sultan, therefore his topography is deficient and his writing style consists of an explicit orthodox nature.[4] He also states that he intentionally suppressed many events, unnatural or strange that he found skeptical that did not fit the objectives he had set down in the preface.[5]
