Umar ibn al-Khattab

“ We shall not display our crosses or our books in the roads or markets of the Muslims. We shall use only clappers in our churches very softly. We shall not raise our voices when following our dead. We shall not show lights on any of the roads of the Muslims or in their markets. We shall not bury our dead near the Muslims. ”

“ This is a letter to the servant of God Umar [ibn al-Khattab] , Commander of the Faithful, from the Christians of such-and-such a city. When you came against us, we asked you for safe-conduct (aman) for ourselves, our descendants, our property, and the people of our community, and we undertook the following obligations toward you:
We shall not build, in our cities or in their neighborhood, new monasteries, Churches, convents, or monks' cells, nor shall we repair, by day or by night, such of them as fall in ruins or are situated in the quarters of the Muslims. ”

“ We shall not mount on saddles, nor shall we gird swords nor bear any kind of arms nor carry them on our- persons.
We shall not engrave Arabic inscriptions on our seals.
We shall not sell fermented drinks. ”
