Nahr al-Sila

In al-Baladhuri: al-Mahdi ordered Nahr al-Sila dug; they dug it and revived the lands along it, assigning its revenue to the sila of the people of the two sanctuaries and their expenses there — the compact offered cultivators who joined it, which they remain on today, fifty years, after which they would sharecrop at half.

Ushri (tithe-land status)

A land status whose holders pay the tithe, not kharaj; in al-Baladhuri the Taff spring-lands the Arabs cultivated after Dhu Qar and the conquest became ushri, likewise the abandoned spring-lands granted after al-Qadisiyya and al-Mada'in — until Ishaq ibn Ibrahim ibn Mus'ab made them Sawadi under al-Mutawakkil.
