This Sayyid, whose name was Abú Muḥammad al-Ḥasan b. 'Alí, had for some time been engaged in study and teaching in Gílán. On the return of al-Bal'amí to Bukhárá, and the arrival of Muḥammad b. Ṣa'lúk at ´Amul, the people of Fajam, Maraz, and all Gíl and Daylam flocked to him. He sent his son Abu`l-Ḥusayn Aḥmad to Rúyán, and thence expelled the Sámánid governor Muhím. Náṣir-i-Kabír then went to Kalár, and there received the allegiance of its Ispahbad Muḥammad b. al-Ḥasan. Thence he pro­ceeded to Gúr-Shír and Jálús, sending on his cousin Ḥasan b. al-Qásim with the vanguard to take Jálús. Muḥammad b. Ṣa'lúk had advanced to Búrábád with 15,000 men. Then a battle was fought (f. 126b), in which Ibn Ṣa'lúk was defeated, and many of his soldiers slain. On a Sunday in Jumáda II, A. H. 301 (= January, A. D. 914) Sayyid Náṣir advanced to Jálús, captured Abu`l-Wafá Khalífa b. Núḥ, slew the Khurásání garrison, and razed the fortress to the ground. Ibn Ṣa'lúk fled by way of ´Amul, Málika Dasht, Sárí and Gurgán to Ray. Two days later Sayyid Náṣir came to ´Amul and established himself in the Palace formerly occupied by Ḥasan b. Zayd. He treated all with the utmost justice, pardoned such as had offended him, and received the allegiance of the people of ´Amul and the neighbourhood. Then 'Abdu`lláh b. al-Ḥasan raised the white standard at Sárí, and summoned the people to support Sayyid Náṣir.
