The Rebellion of Sayyid Náṣir-i-Kabír (f. 124a).

Sayyid Náṣir-i-Kabír’s name was Abú Muḥammad al-Ḥasan b. 'Alí, and he revolted in Gílán and Daylamán, declaring himself “the Avenger” (ath-Thá`ir) of his predecessor, Sayyid Muḥammad b. Zayd, called Dá'i `l-Ḥaqq (“the Propagandist of the Truth”). Isma'íl the Sámánid sent against him his son Aḥmad and his cousin Abu`l-'Abbás 'Abdu`lláh b. Muḥammad b. Núḥ. The armies met at a place called Falás, and the Daylamites were defeated and two thousand of them slain, amongst them the fathers of the afterwards celebrated Mákán [b.] Kákí and of Ḥasan [b.] Fírúzán, the subsequent rulers of Gíl and Daylam.
