KhaybarKhaybar (خَيْبَر, ˈxajbar) is an oasis situated some north of the city of Medina in the Medina Province of Saudi Arabia. Prior to the rise of Islam in the 7th century, the area had been inhabited by Arabian Jewish tribes until it fell to Muslim armies under Muhammad during the Battle of Khaybar in 628 CE. Before the advent of Islam in the 7th century CE, indigenous Arabs and Jews made up the population of Khaybar, but when Jewish settlement in northern Arabia began is unknown.
Constitution of MedinaThe Constitution of Medina (دستور المدينة, Dustūr al-Madīna), also known as the Charter of Medina (صحيفة المدينة, Ṣaḥīfat al-Madīnah; or: ميثاق المدينة, Mīthāq al-Madina "Covenant of Medina"), is the modern name given to a document or documents believed to have formalized the agreement between Muhammad, his followers, and the residents of Medina. Portions of this constitution are corroborated by multiple sound hadith reports. Its validity in its stated single form, however, has been called into question, as there is no single sound chain of authorities (isnad) supporting it.
Pact of UmarThe Pact of Umar (also known as the Covenant of Umar, Treaty of Umar or Laws of Umar; شروط عمر or عهد عمر or عقد عمر), is a treaty between the Muslims and the non-Muslim inhabitants of either Levant (Syria and Lebanon), Mesopotamia (Iraq) or Jerusalem that later gained a canonical status in Islamic jurisprudence. It specifies rights and restrictions for dhimmis, or "people of the book," a type of protected class of non-Muslim peoples recognized by Islam which includes Jews, Christians, Zoroastrians, and several other recognized faiths living under Islamic rule.
