'The Wahhabi Fitna') is a booklet written by Ahmad Zayni Dahlan (1816/17–1886) the Grand Mufti of the Shafi'is in Mecca in the late years of the Ottoman Empire.

[1] Dahlan wrote this work against the Wahhabi creed and he sharply inveighed against it, and called them an evil sect.

[2] The book describes the history of the heretical tenets of Wahhabism in Najd and the Hijaz and the tortures of the Wahhabis inflicted upon Muslims; in which Dahlan exposed and refuted some of what he saw and witnessed from the Wahhabi extreme and terrorist acts and crimes besides their radical beliefs and misguidance in aqidah (Islamic creed).

In Dhu al-Qa'dah of the same year, they laid siege to the area occupied by Muslims, defeated them, and murdered the people, including men, women, and children.

They even stole gifts from the grave of the prophet Muhammad, took all the gold that was there, and engaged in many similar acts of sacrilege.
