Khurasan in the context of "Qutayba ibn Muslim"

Malik Bahauddin Tughril (r. 1195–1210), commonly known as Bahauddin Tughril or Baha al-Din Tughril was a senior Turkic slave of the Ghurid ruler Muhammad of Ghor who was in charge of the Bayana region in the present-day Indian state of Rajasthan. He was admitted into the slave-household of the Ghurids during early reign of Muhammad of Ghor and gradually emerged as one of his eminent slave lieutenant along with Qutb al-Din Aibak, playing a significant role in the Ghurid conquest of northern Indian plain.

After Muhammad of Ghor seized Bayana in 1195–96 to guard the southern flank of Delhi, he made Tughril the viceroy of Bayana. Under his administration, the region of Bayana briefly emerged as a cosmopolitan centre, encouraging considerable Muslim settlements from all over Khurasan. After Muhammad of Ghor's assassination on 15 March 1206, Tughril like other Ghurid mamluks was manumitted, thereby he announced himself as the "Sultan". He died in 1210, and afterwards, the territory was soon brought under by Illtutmish, although Tughril's family continued to exercise influence over the region of Bayana even half a century after his death.

The Mahmud Gawan Madrasa is a former madrasa, now mosque, in partial ruins, located in Bidar, in the state of Karnataka, India. It was completed in 876 AH (1471/1472 CE) and is an example of the regional style of Indo-Islamic architecture under the Bahmani Sultanate. Founded by the prime-minister of the sultanate in the late 15th century, it bears testimony to the scholarly genius of Mahmud Gawan, who first came to Delhi, in exile, as a Persian trader from Gilan in Iran and moved to Bidar in 1453.

Mahmud reportedly built the madrasa with his own money and it functioned like a residential university which was built and maintained on the lines of Madrasa of Khurasan. The imposing and spacious building of the institution is considered as an architectural gem and an important landmark of Bidar.

The Fourth Fitna, Fourth Muslim Civil War, or Great Abbasid Civil War resulted from the conflict between the brothers al-Amin and al-Ma'mun over the succession to the throne of the Abbasid Caliphate. Their father, Caliph Harun al-Rashid, had named al-Amin as the first successor, but had also named al-Ma'mun as the second, with Khurasan granted to him as an appanage. Later a third son, al-Qasim, was designated as third successor. After Harun died in 809, al-Amin succeeded him in Baghdad. Encouraged by the Baghdad court, al-Amin began trying to subvert the autonomous status of Khurasan, and al-Qasim was quickly sidelined. In response, al-Ma'mun sought the support of the provincial élites of Khurasan and made moves to assert his own autonomy. As the rift between the two brothers and their respective camps widened, al-Amin declared his own son Musa as his heir and assembled a large army. In 811, al-Amin's troops marched against Khurasan, but al-Ma'mun's general Tahir ibn Husayn defeated them in the Battle of Ray, and then invaded Iraq and besieged Baghdad itself. The city fell after a year, al-Amin was executed, and al-Ma'mun became Caliph.

Al-Ma'mun chose to remain in Khurasan, however, rather than coming to the capital. This allowed the power vacuum which the civil war had fostered in the Caliphate's provinces to grow, and several local rulers sprang up in Jazira, Syria and Egypt. In addition, a series of Alid uprisings occurred, beginning with Abu'l-Saraya at Kufa and spreading to southern Iraq, the Hejaz, and Yemen. The pro-Khurasani policies followed by al-Ma'mun's powerful chief minister, al-Fadl ibn Sahl, and al-Ma'mun's eventual espousal of an Alid succession in the person of Ali al-Ridha, alienated the traditional Baghdad élites, who saw themselves increasingly marginalized. Consequently, al-Ma'mun's uncle Ibrahim was proclaimed rival caliph at Baghdad in 817, forcing al-Ma'mun to intervene in person. Fadl ibn Sahl was assassinated and al-Ma'mun left Khurasan for Baghdad, which he entered in 819. The next years saw the consolidation of al-Ma'mun's authority and the re-incorporation of the western provinces against local rebels, a process not completed until the pacification of Egypt in 827. Some local rebellions, notably that of the Khurramites, dragged on for far longer, into the 830s.

Shaykh al-Islam (Arabic: شيخ الإسلام, romanized: Shaykh al-ʾIslām, lit. 'Elder (sheikh) of Islam') was used in the classical era as an honorific title for outstanding scholars of the Islamic sciences. It first emerged in Khurasan towards the end of the 4th Islamic century. In the central and western lands of Islam, it was an informal title given to jurists whose fatwas were particularly influential, while in the east it came to be conferred by rulers to ulama who played various official roles but were not generally muftis. Sometimes, as in the case of Ibn Taymiyyah, the use of the title was subject to controversy. In the Ottoman Empire, starting from the early modern era, the title came to designate the chief mufti, who oversaw a hierarchy of state-appointed ulama. The Ottoman Sheikh al-Islam performed a number of functions, including advising the sultan on religious matters, legitimizing government policies, and appointing judges.

With the abolition of the Caliphate in 1924, the official Ottoman office of Shaykh al-Islām, already in decline, was eliminated. Modern times have seen the role of chief mufti carried out by grand muftis appointed or elected in a variety of ways.

Khalid ibn Barmak (709–781/82; Arabic: خالد بن برمك) was the first prominent member of the Barmakids, an important Buddhist family from Balkh, which converted to Islam and became prominent members of the Abbasid court in the second half of the 8th century. Khalid himself converted to Islam at the Umayyad court in the 720s, but joined the nascent Abbasid revolutionary movement in Khurasan, and played a significant role in the Abbasid Revolution that toppled the Umayyads. He enjoyed close relations with the first Abbasid caliph, al-Saffah, functioning as his chief minister and introducing innovations in record-keeping. Under al-Saffah's successor, al-Mansur, Khalid's influence decreased, but he still occupied significant provincial governorships in Fars, Tabaristan, and Mosul. As an administrator, he distinguished himself for his fairness, especially in matters of taxation, and was a popular governor. He appears to have briefly fallen into disgrace around 775, but he managed to recover, helped by the rapid rise of his son, Yahya. Khalid's ties to the Abbasid dynasty were soon strengthened when his grandson, al-Fadl ibn Yahya, became the foster-brother of the future caliph Harun al-Rashid, while Yahya became the prince's tutor. Khalid died in 781/2, shortly after returning from an expedition against the Byzantine Empire.

The Third Fitna (Arabic: الفتنة الثاﻟﺜـة, romanized: al-Fitna al-thālitha), was a series of civil wars and uprisings against the Umayyad Caliphate. It began with a revolt against Caliph al-Walid II in 744, and lasted until 747, when Marwan II emerged as the victor. The war exacerbated internal tensions, especially the Qays–Yaman rivalry, and the temporary collapse of Umayyad authority opened the way for Kharijite and other anti-Umayyad revolts. The last and most successful of these was the Abbasid Revolution, which began in Khurasan in 747, and ended with the overthrow of the Umayyad Caliphate and the establishment of the Abbasid Caliphate in 750.

Bāhila (Arabic: باهلة) was an Arab tribe based in Najd (central Arabia). Part of the tribe was settled and part of it was semi-nomadic. The Bahila was first mentioned during the early years of Islam, in the mid-7th century. During that time, many Bahila tribesmen migrated to Syria and Basra. Many of those who went to Syria later moved to Khurasan as part of the Umayyad garrison there. As a sub-tribe of Qays, they fought alongside the Qaysi coalition against the Yamani tribes during the Umayyad era. The scholar al-Asma'i and the general Qutayba ibn Muslim both belonged to the tribe. The Bahila were last mentioned in the 10th century.
