1. Muhammad ibn Yahya has narrated from ‘Abd Allah ibn Muhammad from Ali ibn al-Hakam and Humayd ibn Ziyad from al-Hassan ibn Muhammad from more than one person from Aban ibn ‘Uthman from ‘Isma’il ibn al-Fadl al-Hashimiy who has said the following: “This is concerning my question before abu ‘Abd Allah عليه السلام, about the case of a man who rents, from al-Sultan a piece of land of al-Kharaj that belongs to tax payers, because of the failure of the owners. He (the Imam) said, ‘If the owners fail, you can take such land unless it is harmful to the owners. If you pay a certain amount to the owners and it helps to make them agree, then you can have such land.’ I then asked him (the Imam) about the case of a man who bought a piece of al-Kharaj land, then built in it or not except that tax payer people arrived therein, if he could receive the rent of houses from them if they pay taxes on their persons. He (the Imam) said, ‘He must stipulate it with them and after stipulation it is lawful.’”
