"There is another mandate relating to those subjects who are unbelievers and protected people (zimmis). For their governance, the observance of those conditions that the Caliph ‘Umar laid down in his agreement for establishing the status of the fire worshipers and the People of the Book [Jews and Christians], and which gave them safety, is obligatory on rulers and governors. Rulers should impose these conditions on the zimmis of their dominions and make their lives and their property dependent on their fulfillment. The twenty conditions are as follows: 1. In a country under the authority of a Muslim ruler, they are to build no new homes for images or idol temples. 2. They are not to rebuild any old buildings that have been destroyed. 3. Muslim travelers are not to be prevented from staying in idol temples. 4. No Muslim who stays in their houses will commit a sin if he is a guest for three days, if he should have occasion for the delay. 5. Infidels may not set as spies or give aid and comfort to them. 6. If any of their people show any inclinations toward Islam, they are not to be prevented from doing so. 7. Muslims are to be respected. 8. If zimmis are gathered together in a meeting and Muslims appear, they are to be showed st the meeting. 9. They are not to dress like Muslims. 10. They are not to give each other Muslim names. 11. They are not to ride on horses with saddle and bridle. 12. They are not to possess swords and arrows. 13. They are not to wear signet rings and seals on their fingers. 14. They are not to sell and drink intoxicating liquor openly. 15. They must not abandon the clothing that they have had as a sign of their state of ignorance so that they may be distinguished from Muslims. 16.

They are not to bring their dead near the graveyards of Muslims. 119. They are not to mourn their dead with loud voices. 20. They are not to buy Muslim slaves. At the end of the treaty it is written that if zimmis infringe any of these conditions, they shall not enjoy security and it shall be lawful for Muslims to take their lives and possessions as though they were the lives and possessions of unbelievers in a state of war with the faithful."
