NajdNajd (نَجْدٌ, nad͡ʒd) is the geographic center of Saudi Arabia, accounting for about a third of the country's modern population and, since the Emirate of Diriyah, acting as the base for all unification campaigns by the House of Saud to bring Arabia under a single polity. Historic Najd was divided into three modern administrative regions still in use today. The Riyadh region, featuring Wadi Hanifa and the Tuwaiq escarpment, which houses easterly Yamama with the Saudi capital, Riyadh since 1824, and the Sudairi region, which has its capital in Majmaah.
HejazThe Hejaz (hiːˈdʒæz,_hɪˈ-, also UShɛˈ-; al-Ḥijāz, alħɪˈdʒaːz) is a region which includes the majority of the west of Saudi Arabia, which includes the cities of Mecca, Medina, Jeddah, Tabuk, Yanbu, Taif and Baljurashi. It is thus known as the "Western Province", and is bordered in the west by the Red Sea, in the north by Jordan, in the east by the Najd, and in the south by the Region of 'Asir. It is the most cosmopolitan region in the Arabian Peninsula.
MedinaMedina, officially Al-Madinah al-Munawwarah (المدينة المنورة, almadiːna almʊnawːara) and also commonly simplified as Madīnah or Madinah (المدينة, almadiːna), is the capital of Medina Province in the Hejaz region of western Saudi Arabia. One of the most sacred cities in Islam, the estimated population as of 2020 is 1,488,782, making it the fourth-most populous city in the country.
Abu BakrAbū Bakr ʿAbd Allāh ibn ʿAbī Quḥāfa (; 27 October 573 – 23 August 634) was the senior companion and was, through his daughter Aisha, a father-in-law of the Islamic prophet Muhammad, as well as the first Caliph of the Rashidun Caliphate. He is known with the honorific title al-Siddiq by Sunni Muslims. Abu Bakr was born in 573 CE to Abu Quhafa and Umm Khayr. He belonged to the tribe of Banu Taym. In the Age of Ignorance, he was a monotheist and condemned idol-worshipping. As a wealthy trader, Abu Bakr used to free slaves.
JizyaJizya (جِزْيَة ALA / DIN d͡ʒɪzjæ) is a per capita yearly taxation historically levied in the form of financial charge on dhimmis, that is, permanent non-Muslim subjects of a state governed by Islamic law. The Quran and hadiths mention jizya without specifying its rate or amount, and the application of jizya varied in the course of Islamic history. However, scholars largely agree that early Muslim rulers adapted existing systems of taxation and tribute that were established under previous rulers of the conquered lands, such as those of the Byzantine and Sasanian empires.

Battle of the TrenchThe Battle of the Trench (Ghazwat al-Khandaq), also known as the Battle of Khandaq (Ma’rakah al-Khandaq) and the Battle of the Confederates (Ghazwat al-Ahzab), was part of the conflict between the Muslims and the Quraysh, where this time the Quraysh took the offensive and advanced on the Muslims, who defended themselves in Medina by digging a trench around their settlement at the suggestion of Salman the Persian. The battle, which took place in 627 and lasted around two weeks, was lightly fought, with the Muslims reported to have suffered five to six casualties and the Quraysh three.
SheikhSheikh (pronounced ʃeɪk or ʃiːk ; شيخ DIN ʃajx, commonly ʃeːx, plural شيوخ DIN ʃujuːx) is an honorific title in the Arabic language, literally meaning "Elder"; in a monarchical context it is also translated as "Lord/Master". It commonly designates a chief of a tribe or a royal family member in Arabian countries, or a Muslim religious scholar. It is also used as an honorary title by people claiming to be descended (either patrilineally or matrilineally) from Hasan ibn Ali or Husayn ibn Ali, grandsons of the Islamic prophet Muhammad.
HijrahThe Hijrah or Hijra (الهجرة) was the journey of the Islamic prophet Muhammad and his followers from Mecca to Medina. The year in which the Hijrah took place is also identified as the epoch of the Lunar Hijri and Solar Hijri calendars; its date equates to 16 July 622 in the Julian calendar. The Arabic word hijra means primarily "a severing of ties of kinship or association." It has been also transliterated as Hegira in medieval Latin, a term still in occasional use in English.
HawazinThe Hawazin (هوازن / ALA-LC: Hawāzin) were an Arab tribe originally based in the western Najd and around Ta'if in the Hejaz. They formed part of the larger Qays tribal group. The Hawazin consisted of the subtribes of Banu Sa'd, and Banu Jusham, as well as the powerful Banu Thaqif and Banu Amir, which were both often counted separately from the Hawazin. The tribe often clashed with their one-time patrons, the Ghatafan, and on occasion, sub-tribes of the Hawazin fought each other.
