9. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from al-Kahiliy from Mansur ibn Hazim who has said the following: “This is concerning my question before abu ‘Abd Allah , about the case of a house which a certain people divided, each one took a piece, built and left in between a courtyard with the driveway on it. A man came and bought the share of someone among them; if he can do so. He (the Imam) said, ‘Yes, he can do so but he must close his door and open a door to a driveway or climb down from the top of the house and close its door. When the owner of the driveway decides to sell, they have the right more than others, otherwise, it is the pathway through which he comes to set on that door.’”
