Islamic civilization had a significant impact on the Turkic peoples, particularly in the context of cultural and literary developments such as dastans. Dastans are traditional epic narratives that combine prose and poetry, often recounting heroic tales, historical events, and moral lessons. The influence of Islamic civilization on these narratives can be seen in several ways:

1. Introduction of Islamic Themes: With the spread of Islam among the Turkic peoples, Islamic themes and values began to permeate dastans. This included the incorporation of Islamic moral and ethical teachings, as well as references to Islamic history and figures.

2. Language and Literature: The adoption of the Arabic script and the influence of Persian and Arabic literature enriched the literary tradition of the Turkic peoples. This led to the development of a more sophisticated literary style in dastans, incorporating elements from Islamic literature.

3. Cultural Exchange: The interaction between Islamic civilization and the Turkic peoples facilitated a cultural exchange that influenced the content and form of dastans. This exchange introduced new storytelling techniques and motifs that were integrated into the traditional narratives.

4. Preservation and Transmission: Islamic institutions, such as madrasas and libraries, played a role in the preservation and transmission of dastans. These institutions helped in documenting and disseminating these narratives, ensuring their survival and continued evolution.

Overall, the impact of Islamic civilization on the Turkic peoples in relation to dastans was profound, leading to a rich synthesis of cultural and literary traditions that continue to be celebrated in the Turkic world today.
