I asked Imam (as) about farming partnerships with the people of kharaj lands based on a quarter, a third, or half of the yield. Imam (as) said: "There is no harm in it. Indeed, the Messenger of Allah (swt) (peace and blessings be upon him and his family) made an agreement with the Jews of Khaybar when it was conquered, granting them the land based on 'al-khabr,' and 'al-khabr' means half."
