Rent From Tenant and His Responsibilities

3. Ahmad ibn Muhammad has narrated from Ibn Abi ‘Umayr from Ali ibn ‘Isma’il ibn ‘Ammar from ‘Ubayd ibn Zurarah who has said the following: “This is concerning my question before abu ‘Abd Allah عليه السلام, about the case of a man who comes to another man and says, ‘Write for me for a few dirham.’ He says, ‘I take from you and write (in your presence).’ He (the Imam) said, ‘It is not unlawful.’ I then asked about a man who hires a slave who says, ‘Make my master agree for whatever amount you like but so and so much dirham will be for me’, if this becomes binding upon the employer and if it is lawful for the slave. He (the Imam) said, ‘It does not become binding upon the employer and it is not lawful for the slave.’”
