These rules listed below are not inventions of the Islamic State. They are as old as the concept of dhimmitude itself. Compare the Islamic State’s rules to the rules for dhimmis enunciated in Umdat al-Salik (Reliance of the Traveller), a classic manual of Islamic law:
O11.4: The Non-Muslim Poll Tax
The minimum non-Muslim poll tax is one dinar (n: 4.235 grams of gold) per person (A: per year). The maximum is whatever both sides agree upon.
It is collected with leniency and politeness, as are all debts, and is not levied on women, children, or the insane.
O11.5
Such non-Muslim subjects are obliged to comply with Islamic rules that pertain to the safety and indemnity of life, reputation, and property. In addition, they:

-2- are distinguished from Muslims in dress, wearing a wide cloth belt (zunnar);
-3- are not greeted with “as-Salamu ‘alaykum”;
-4- must keep to the side of the street;
-5- may not build higher than or as high as the Muslims’ buildings, though if they acquire a tall house, it is not razed;

-7- and are forbidden to build new churches.
