Take only the kharaj from those who cultivate the land, so that they are treated gently and find ease. I command you to take only the weight of seven in kharaj, do not take the wages of the money-changers. Do not take melted silver. Do not take the gifts of Nowruz and Marjan. Do not take the price of the scriptures. Do not take the wages of the scribes, do not take the rent of rooms, do not take the dirham for marriage, and do not take kharaj from anyone who becomes a Muslim.
