Rafi‘ b. Khadij reported the Prophet as saying, “If anyone sows in other people’s land without their permission he has no right to any of the crop, but he may have what it cost him.”
Tirmidhi and Abu Dawud transmitted it, Tirmidhi saying this is a gharib tradition.
Abu Umama on seeing a ploughshare and some agricultural instruments told that he had heard the Prophet say, “This will not enter any people’s house without God causing ignominy to enter it*.”
Bukhari transmitted it.
*This tradition says that agriculture is a less noble occupation than jihad.
Qais b. Muslim told that Abu Ja'far said there was not a family of the Emigrants who did not cultivate ground for a third and a quarter of the produce, and ‘Ali, Sa‘d b. Malik, ‘Abdallah b. Mas'ud, ‘Umar b. ‘Abd al-Aziz, al-Qasim, ‘Urwa, the family of Abu Bakr, the family of ‘Umar, the family of ‘Ali, and Ibn Sirin made contracts for part of the produce in return for working land. ‘Abd ar-Rahman b. al- Aswad said that he partnered 'Abd ar-Rahman b. Yazid in cultivation, and ‘Umar employed people on condition that if he provided the seed he should have half the crop, and if they provided the seed they should have such and such.
Jabir reported God’s Messenger as saying, “If anyone has land he should cultivate it, or lend it to his brother; but if he refuses he should retain his land.”
