My uncle sent me and his slave to Sa’id ibn al-Musayyab. We said to him, there is something which has reached us about sharecropping. He replied: Ibn Umar did not see any harm in it until a tradition reached him from Rafi’ ibn Khadij. He then came to him and Rafi’ told him that the Messenger of Allah (ﷺ) came to Banu Harithah and saw crop in the land of Zuhayr. He said: What an excellent crop of Zuhayr is! They said: It does not belong to Zuhayr. He asked: Is this not the land of Zuhayr? They said: Yes, but the crop belongs to so-and-so. He said: Take your crop and give him the wages. Rafi’ said: We took our crop and gave him the wages. Sa’id (ibn al-Musayyab) said: Lend your brother or employ him for dirhams.
