The Nine Books of Hadith (Al-Kutub al-Tis'ah) represent the most primary and widely respected collections of recorded sayings, actions, and approvals of the Prophet Muhammad in Sunni Islam.

Significance: Highly organized topical collection often included to complete the nine primary texts due to the authenticity of its narrators.
