Muhammad al-Bukhari in the context of "Nishapur"

Kutub al-Sittah (Arabic: ٱلْكُتُب ٱلسِّتَّة, romanized: al-Kutub al-Sitta, lit. 'the Six Books'), also known as al-Sihah al-Sitta (Arabic: الصحاح الستة, romanized: al-Ṣiḥāḥ al-Sitta, lit. 'the Authentic Six') are the six canonical hadith collections of Sunni Islam. They were all compiled in the 9th and early 10th centuries, roughly from 840 to 912 CE and are thought to embody the Sunnah of Muhammad.

The books are the Sahih of al-Bukhari (d. 870), the Sahih of Muslim ibn al-Hajjaj (d. 875), the Sunan of Abu Dawud (d. 889), the Sunan of al-Tirmidhi (d. 892), the Sunan of al-Nasa'i (d. 915), and the Sunan of Ibn Majah (d. 887 or 889) as the sixth book, though some (particularly the Malikis and Ibn al-Athir) instead listed the Muwatta of Malik ibn Anas (d. 795) as the sixth book, and other scholars list Sunan of al-Daraqutni (d. 995) as the sixth book. Sunan ibn Majah largely won out as the sixth canonical book because its content has less overlap with the other five compared with its two contenders.

In Islam, "the promise and threat" (waʿd wa-waʿīd) of Judgement Day (Arabic: یوم القيامة, romanized: Yawm al-qiyāmah, lit. 'Day of Resurrection' or Arabic: یوم الدین, romanized: Yawm ad-din, lit. 'Day of Judgement'), is when "all bodies will be resurrected" from the dead, and "all people" are "called to account" for their deeds and their faith during their life on Earth. It has been called "the dominant message" of the holy book of Islam, the Quran, and resurrection and judgement the two themes "central to the understanding of Islamic eschatology."Judgement Day is considered a fundamental tenet of faith by all Muslims, and one of the six articles of Islamic faith.

The trials, tribulations, and details associated with it are detailed in the Quran and the Hadith (sayings of Muhammad); these have been elaborated on in creeds, Quranic commentaries (tafsịrs), theological writing, eschatological manuals to provide more details and a sequence of events on the Day. Islamic expositors and scholarly authorities who have explained the subject in detail include al-Ghazali, Ibn Kathir, Ibn Majah, Muhammad al-Bukhari, and Ibn Khuzaymah.

Sahih al-Bukhari (Arabic: صحيح البخاري, romanized: Ṣaḥīḥ al-Bukhārī) is the first hadith collection of the Six Books of Sunni Islam. Compiled by Islamic scholar al-Bukhari (d. 870) in the musannaf format, the work is valued by Sunni Muslims, alongside Sahih Muslim, as the most authentic after the Qur'an.

Al-Bukhari organized the book mostly in the Hijaz at the Sacred Mosque of Mecca and the Prophet's Mosque of Medina and completed the work in Bukhara around 846 (232 AH). The work was examined by his teachers Ahmad ibn Hanbal, Ali ibn al-Madini, Yahya ibn Ma'in and others.

Islam is the dominant religion in Uzbekistan. Islamic customs were broadly adopted by the ruling elite, and they began patronage of scholars and conquerors such as Muhammad al-Bukhari, Al-Tirmidhi, Ismail Samani, al-Biruni, Avicenna, Tamerlane, Ulugh Begh, and Babur. Despite its predominance and history, the practice of Islam has been far from monolithic since the establishment of the Uzbek Soviet Socialist Republic.

The Muslim Board of Uzbekistan holds the Mushaf Othmani, the earliest existing copy of the Quran.

The Black Guard or ‘Abid al-Bukhari (Arabic: عبيد البخاري, lit. 'Slaves of al-Bukhārī'; also known as ‘Abīd ad-Dīwān "slaves of the diwan", Jaysh al-‘Abīd "the slave army", and ‘Abid as-Sultan "the sultan’s slaves") were the corps of black-African slaves and Haratin slave-soldiers assembled by the 'Alawi sultan of Morocco, Isma‘il ibn Sharif (reigned 1672–1727). They were called the "Slaves of Bukhari" because Sultan Isma‘il emphasized the importance of the teachings of the famous imam Muhammad al-Bukhari, going so far as to give the leaders of the army copies of his book. This military corps, which was loyal only to the sultan, was one of the pillars of Isma'il's power as he sought to establish a more stable and more absolute authority over Morocco.

After Isma'il's death, the Black Guard became one of the most powerful factions in Moroccan politics and played the role of kingmakers during the period of turmoil that followed. Over the course of the later 18th century and the 19th century their role in the military was progressively reduced and their political status varied between privilege and marginalization. Their descendants eventually regained their freedom and resettled across the country. While black Africans lived in the region long before Isma'il's reign, a long-term consequence of his policies was the introduction and eventual dispersal of a substantial new black population in Morocco.
