The first 'Abbásid governor of Ṭabaristán was the already-mentioned Abu`l-Khuḍayb, and the first building erected there by the Muslims was the Great Mosque of Sárí, which he caused to be built on a Monday in the month of ´Abán in the year A. H. 140 (A. D. 757—8), on which date ´Amul was occupied and Ṭabaristán practically conquered by the Muslims. Abu`l-Khuḍayb was governor for two years, and was succeeded by Abú Khuzayma, who settled armed gar­risons throughout the country as follows: in Tammísha 1000 Arabs under Fakhr b.

After a year [? Abu`l-Khuzayma] was dismissed, and replaced by Rúḥ b. Ḥátim b. Qayṣar b. al-Muhallab, who was made governor in A. H. 144 (= A. D. 761—2), but a year later, being convicted of tyranny and injustice, he was replaced by Khálid b. Barmak, who took up his abode at a place called after him Khálida-Saráy. He also built for himself a palace at ´Amul, and ruled for four years, building many public buildings and developing the resources of the country, until at the end of this period he was replaced by ‘Amr b. al-'Alá, during whose governorship the Caliph al-Manṣúr died, and was succeeded by (f. 88b) his son al-Mahdí. He, being informed that 'Amr b. al-'Alá had sought the hand of the daughter of Mihrúya in marriage, was angered against him and dismissed him. Sa'íd b. Da'laj succeeded him as governor, and held this position for three years. At this period a Sayyid of the House of Abú Tálib named Ḥusayn b. 'Alí, commonly called <Arabic>, revolted in the Ḥijáz, and was joined by many other Sayyids. The Caliph sent Músá b. 'Isá and Sirrí b. 'Abdu`lláh al-'Abbásí, with other Amírs and officers, to fight him. The Battle took place at Fakhkh, and the Sayyid was slain, together with many of his companions. Some few, however, escaped, and made their way to al-Madína, where Músá b. 'Isá was holding his court and audience, at which, to avert suspicion of disaffection, most of the chief men of al-Madína were present. Presently Músá b. 'Abdu`lláh b. al-Ḥasan b. al-Ḥasan b. 'Alí b. 'Abí Ṭálib, who had escaped from the battle, came in, clad in a course woollen cuirass (<Arabic>), slashed with sword-cuts, and sandals of camel’s skin, and sat down in the lowest place. Immediately afterwards the Imám Músá b. Ja'far al-Kádhim entered. Músá b. 'Isá rose to meet him, and caused him to sit in an honourable place. Sirrí b. 'Abdu`lláh al-'Abbásí turned to Músá b. 'Abdu`lláh b. al-Ḥasan and said, “What dost thou think of the stricken field of rebellion and treachery? Why dost thou not withhold thy hand from such deeds, that thy cousins (meaning the 'Abbásids) might enrich thee and treat thee with honour?” Músá replied, “Our relation towards you is like what has been said in this verse:”

“Good!” exclaimed Sirrí; “it is even so: naught accrues to you save abasement and humiliation. If you would only be quiet as is ỵour cousin here, Músá b. Ja'far, notwith­standing all his learning, piety, nobility and ascetic life (f. 89a), would it not be better?” Thereupon Músá b. 'Abdu`lláh extemporised the following verses:

<Arabic>

Now since the Caliph al-Mahdí was preoccupied with these matters, Sa'íd b. Da'laj remained two years and three months as Governor of Ṭabaristán ere he was recalled, and 'Amr b. al-'Alá was again sent to replace him. He it was who built the village of 'Amr (? 'Umar) Kaláda, situated near Wana-bun, as well as another town called 'Umar (? Amr)-ábád. In this year there was a great earthquake; and Aḥmad b. Ḥanbal declared at Baghdad that heavier taxes should be imposed on the people of Ṭabaristán, as well as a 10% tithe on cereals, because the country had not surrendered willingly, but had been taken by force. A year later 'Amr b. al-'Alá was replaced by Yaḥyá b. Mikhnáq (B. <Arabic>), who dealt gently with the people, till he was in turn replaced by 'Abdu`l-Ḥamíd Maḍrúb, who vexed the people with new and oppressive taxes.
