Muslims are people who adhere to Islam, a monotheistic religion belonging to the Abrahamic tradition. They consider the Quran, the foundational religious text of Islam, to be the verbatim word of the God of Abraham as it was revealed to Muhammad, the main Islamic prophet. Alongside the Quran, Muslims also believe in previous revelations, such as the Tawrat (Torah), the Zabur (Psalms), and the Injeel (Gospel). These earlier revelations are associated with Judaism and Christianity, which are regarded by Muslims as earlier versions of Islam. The majority of Muslims also follow the teachings and practices attributed to Muhammad (sunnah) as recorded in traditional accounts (hadith).
The terms Muslim world and Islamic world commonly refer to the Islamic community, which is also known as the Ummah. This consists of all those who adhere to the religious beliefs, politics, and laws of Islam or to societies in which Islam is practiced. In a modern geopolitical sense, these terms refer to countries in which Islam is widespread, although there are no agreed criteria for inclusion. The term Muslim-majority countries is an alternative often used for the latter sense.
The Catholic Church is "the Catholic Communion of Churches, both Roman and Eastern, or Oriental, that are in full communion with the Bishop of Rome ."

According to Vatican II's Gaudium et spes, the "church has but one sole purpose–that the kingdom of God may come and the salvation of the human race may be accomplished."

According to a PEW estimation in 2020, Christians made up to 2.38 billion of the worldwide population of about 8 billion people. It represents nearly one-third of the world's population and is the largest religion in the world, with the three largest groups of Christians being the Catholic Church, Protestantism, and the Eastern Orthodox Church. The largest Christian denomination is the Catholic Church, with 1.3 billion baptized members. The second largest Christian branch is either Protestantism, or the Eastern Orthodox Church.
Jaʽfar ibn Yahya Barmaki or Jafar al-Barmaki (767–803), also called Aba-Fadl, was a Persian vizier of the Abbasid caliph Harun al-Rashid, succeeding his father in that position. He was a member of the influential Barmakid family, formerly Buddhist leaders of the Nava Vihara monastery. He was executed in 803 at the orders of Harun al-Rashid.
Yahya ibn Khalid was the most prominent member of the Barmakid family, serving as provincial governor and all-powerful long-time vizier to Caliph Harun al-Rashid before his abrupt fall in 803.
Khalid ibn Barmak 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.

Adherents of Islam constitute the world's second largest and fastest growing major religious grouping, maintaining suggested 2017 projections in 2022. As of 2020, Pew Research Centre (PEW) projections suggest there are a total of 1.9 billion adherents worldwide. Further studies indicate the worldwide spread and percentage growth of Islam, may be attributed to high birth rates followed by a trend of worldwide adoption and conversion to Islam.

Yaḥyā ibn ʿAbd Allāh ibn al-Ḥasan ibn al-Ḥasan ibn ʿAlī ibn Abī Ṭālib was an Alid and Zaydi leader who led a rebellion against the Abbasid caliph Harun al-Rashid in Daylam in 792. He was soon obliged to capitulate, but his activity began the spread of Zaydi Islam in the remote mountains of Daylam. After his surrender, he was initially treated with much honour, but Harun remained deeply suspicious of his popularity and intentions, and recalled him to Baghdad, where he spent the remainder of his life in prison. In 802, the Barmakid Ja'far ibn Yahya helped him escape, but he was captured; the event led to the execution of the Barmakids, once Harun's closest companions. Yahya died in prison, probably in 803.
Muhammad ibn Khalid ibn Barmak was one of the Barmakids, a family of Iranian functionaries who rose to great power under the Abbasid caliph Harun al-Rashid.
