Musannaf Ibn Abi Shaybah 34905 — What they said on the fifth

Abu Awn Muhammad bin Ubaydullah al-Thaqafi (may Allah have mercy on him) said that Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) imposed on the people of Sawad, on every jarib of land that water reaches, whether cultivated or uncultivated, one dirham and one qafiz of food. On orchards, on every jarib, he imposed ten dirhams and ten qafiz of food. On green crops, on every jarib, he imposed five dirhams and five qafiz of food. On vineyards, on every jarib, he imposed ten dirhams and ten qafiz. On date palms he imposed nothing, and he treated them as subordinate to the land.
