Al-Layth ibn al-Fadl al-Abiwardi (Arabic: الليث بن الفضل الأبيوردي) was a provincial governor for the Abbasid Caliphate, serving in Egypt (798–803) and Sistan (815–819).
[5] Despite their defeat, the Hawfis persisted in their refusal to pay their taxes, and al-Layth eventually decided to make a visit to Harun al-Rashid in order to request reinforcements.
When al-Layth reached the provincial capital of Zaranj in December 815 he occupied it with 400 cavalrymen and purged the city of Harb's loyalists, but he soon realized that the rebels enjoyed a significant numerical advantage in the countryside.
Eventually the rebels were defeated in a decisive battle; Harb subsequently disappeared, while Ibn al-Ash'ath fled to Zaranj but was captured, mutilated and killed by al-Layth.
As a result of the peaceful state of affairs, the province soon came to enjoy a period of economic prosperity, with construction activity and trades of estates experiencing a significant boom during al-Layth's administration.
