Abu'l-Sarāyā al-Sarī ibn Manṣūr al-Shaybānī (d. 18 October 815) was leader of a Zaydi revolt against the Abbasid Caliphate in Kufa and Iraq in 815. The revolt spread quickly across southern Iraq, and his agents even took over Mecca and Medina. At one point, the rebels threatened even Baghdad, but the Abbasid general Harthama ibn A'yan drove them back to Kufa in a series of victories. Forced to abandon Kufa in late August, Abu'l-Saraya and his followers tried to flee, but were pursued, defeated, and captured. Abu'l-Saraya himself was executed at Baghdad on 18 October. The uprising continued in the Hejaz for a few months under Muhammad ibn Ja'far al-Sadiq as anti-caliph at Mecca, until this too was suppressed by the Abbasid troops.
Life
Abu'l-Saraya's early life is obscure. His hometown was Ras al-Ayn, and claimed descent from the pre-Islamic Shabani chieftain Hani ibn Qabisah, but is said to have been a donkey driver and a bandit, before he entered the service of Yazid ibn Mazyad al-Shaybani, the Abbasid governor of Armenia. Under Yazid's command, he fought against the Khurramites. In the Abbasid civil war of al-Amin and al-Ma'mun, he initially sided with the former, and fought against al-Ma'mun's general Harthama ibn A'yan, before switching sides.
Revolt in Kufa
After a while, he obtained leave to go to the Hajj, but on the way rose on revolt. He defeated the Abbasid troops sent against him, and with the Alid Ibn Tabataba launched a Zaydi-inspired uprising in Kufa in January 815. Ibn Tabataba's role in the revolt was only as a figurehead, while actual power rested with Abu'l-Saraya. Indeed, modern scholars suggest that Abu'l-Saraya was not motivated by pro-Alid zeal, but merely saw the Alids as a tool to gain power.
The uprising was initially successful, and on 14 February 815, the rebels defeated the Abbasid troops under Zuhayr ibn al-Musayyab, that al-Ma'mun's governor of Iraq, al-Hasan ibn Sahl, had sent against them. On the next day, Ibn Tabataba died—poisoned by Abu'l-Saraya, according to al-Tabari, although this is likely a fabrication—and Muhammad ibn Muhammad ibn Zayd was made imam in his stead.
Spread of the uprising
The Abbasid commander, Zuhayr ibn al-Musayyab, withdrew to Qasr Ibn Hubayra, but at the same time, another Abbasid army of 4,000 cavalry under Abdus ibn Muhammad was sent against Kufa by al-Hasan ibn Sahl. On 3 March, Abu'l-Saraya defeated Abdus, who fell in battle. His men were either killed or taken prisoner. On the news of this, Ibn al-Musayyab withdrew further north, to Nahr al-Malik, while Abu'l-Saraya led his own troops to Qasr Ibn Hubayra.
Following his victory, Abu'l-Saraya minted dirhams with the inscription "God loves those who fight in His way in ranks, as though they were a building well-compacted", and sent his followers to occupy Wasit, Basra, and Ahwaz. At Wasit, Abu'l-Saraya's men scored another victory against the local governor, Abdallah ibn Sa'id al-Harashi, who had to retreat to Baghdad with heavy losses.
Abu'l-Saraya also sent other Alids as his agents to take over Mecca and Medina. Muhammad ibn Sulayman ibn Dawud ibn al-Hasan al-Muthanna, who was sent to Medina, was successful and took the city without opposition. Husayn ibn Hasan al-Aftas ibn Ali ibn Husayn Zayn al-Abidin, sent to Mecca, hesitated to enter the city due to the presence of an Abbasid garrison in the city that accompanied the annual Hajj pilgrimage. However, the Abbasid governor, Dawud ibn Isa, was also reluctant to confront the rebels and shed blood in the sacred city, even while the local garrison commander, Masrur al-Kabir, favoured confronting them. In the end, Dawud ibn Isa abandoned the city with part of the Abbasids' followers, and Masrur al-Kabir, his forces depleted and fearful of the pilgrims joining the rebels, followed within days. Husayn ibn Hasan al-Aftas and his small entourage entered the city on the Day of Arafah (21 June). From Mecca, another Alid, Ibrahim ibn Musa al-Kadhim, set out and took over rule of the Yemen for a while.
Defeat, capture, and death
The rebels now threatened Baghdad itself, forcing al-Hasan ibn Sahl to seek the assistance of Harthama, who was on his way to Khurasan. After initial reluctance, he agreed and returned to Baghdad. Learning of this, in April/May Abu'l-Saraya advanced to al-Mada'in, and even onwards to Nahr Sarsar, just south of Baghdad. There Harthama arrived with his own forces, and confronted the rebel army across the canal linking the Tigris and Euphrates rivers.
