4. A number of our people have narrated from Ahmad ibn Muhammad from al-Hassan ibn Mahbub from al-Husayn ibn Sa‘id from al- Nadr ibn Suwayd from ‘Abd Allah ibn Sinan who has said the following: “About the case of a man who works in sharecropping, cultivates the land of another man and says, ‘One third for the bulls, one-third for the seed and one-third for the land’, he (the Imam) Alayhi al- Salam, has said, ‘Things like bulls, seeds and so on must not be mentioned, instead he must say, “You must cultivate so and so items, if you want for one-half or if you want for one-third.’””
