al-Hajjaj's Daylam Expedition

بعث الحجاج إلى الديلم

Daylam

When the Kurds ravaged during Ibn al-Ash'ath's revolt, al-Hajjaj sent Amr ibn Hani' al-Absi with Damascenes who routed and slaughtered them, then ordered him against Daylam with twelve thousand — among them eighty of Banu Ujul and their Kufan clients, including Muhammad ibn Sinan al-Ujli, who settled a Dastaba village then built a house in Qazwin's suburb; the frontier folk rebuked him for exposing himself and them, he ignored them, his household built with him outside the town, others followed, and so the suburb grew.

Overview

In the days of the rising of Abd al-Rahman ibn Muhammad ibn al-Ash'ath, the Kurds raided and spread corruption. Al-Hajjaj sent Amr ibn Hani al-Absi against the people of Damascus, who defeated them and killed a great number. 1

The expedition against the Daylam

Then al-Hajjaj ordered him to raid the Daylam, and he raided them with twelve thousand men. Among them were eighty of the Banu Ajl and their clients from Kufa, among them Muhammad ibn Sinan al-Ujli. 1

The origin of the quarter of Qazwin

Muhammad ibn Sinan settled in a village of the villages of Dastabi, then went on to Qazwin and built a house in its outer quarter. The people of the frontier blamed him, but he paid no heed. His household built outside the city with him, and then the people moved and built until the outer quarter of the city was complete. 1

The date of the expedition is not given in the entity data. An additional source is needed.

Abd al-Malik's Coinage Reform

Heraclius's dinars and the Persian Baghliyya dirhams reached Jahiliya Mecca and traded only as bullion: their mithqal twenty-two qirats less a fraction, ten dirhams seven mithqals, the ratl twelve uqiyyas of forty dirhams — weights the Prophet confirmed, and Abu Bakr, Umar, Uthman, Ali, and Mu'awiya after him. Mus'ab ibn al-Zubayr struck a few dirhams under Ibn al-Zubayr, later broken; then Abd al-Malik asked and tested, wrote al-Hajjaj to strike dirhams at fifteen qirats of the dinar-qirats, and struck the Damascene dinars — which came to Medina with Companions and Followers there and none objected. Al-Hasan ibn Salih: the Ajam dirhams ran great and small — twenty, twelve, ten qirats — and when Islam needed the mean for zakah they summed forty-two and struck the third, fourteen qirats, so ten Arab dirhams weigh seven mithqals. Quraysh's weights: the dirham for silver, the dinar for gold, ten dirham-weights to seven dinar-weights, the sha'ira a sixtieth of a dirham, the uqiyya forty dirhams, the nashsh twenty, the nawa five — all confirmed when the Prophet entered Mecca. And Sa'id ibn al-Musayyab, asked who first struck engraved dinars, said 'Abd al-Malik ibn Marwan — dinars came Byzantine, dirhams Kisrawi and few Himyari'.
