Musannaf Ibn Abi Shaybah 39793 — Reports on the people of Najran

It is narrated from Yahya bin Sa'id that Sayyiduna Umar (may Allah be pleased with him) exiled the people of Najran, the Jews and the Christians, and purchased their lands and their grapevines. Sayyiduna Umar made an arrangement (with the people) that if they themselves provided the oxen and the plough equipment, they would receive two-thirds (of the produce) and Sayyiduna Umar one-third, and if Sayyiduna Umar provided the seed, he would receive half. And Sayyiduna Umar made an arrangement with them over the date palms on the condition that one-fifth (of the produce) would be theirs and four-fifths Sayyiduna Umar's, and over the grapevines on the condition that their share would be one-third and Sayyiduna Umar's share two-thirds.
