Seal of the Prophets in the context of "Death of Muhammad"

Islam is an Abrahamic monotheistic religion based on the Quran and the teachings of Muhammad. Adherents of Islam are called Muslims, who are estimated to number 2 billion worldwide and are the world's second-largest religious population, after Christianity.

Muslims believe that there is a primordial faith that was revealed many times through earlier prophets and messengers, including Adam, Noah, Abraham, Moses, and Jesus, and they believe that Islam is the universal and complete version of this faith. Muslims consider the Quran to be the verbatim word of God and the unaltered, final revelation. Alongside the Quran, Muslims also believe in previous revelations, such as the Tawrat (the Torah), the Zabur (Psalms), and the Injil (Gospel). They believe that Muhammad is the main and final of God's prophets, through whom the religion was completed. The teachings and normative examples of Muhammad, called the Sunnah, documented in accounts called the hadith, provide a constitutional model for Muslims. Islam is based on the belief in the oneness and uniqueness of God (tawhid), and belief in an afterlife (akhirah) with the Last Judgment—wherein the righteous will be rewarded in paradise (jannah) and the unrighteous will be punished in hell (jahannam). The Five Pillars, considered obligatory acts of worship, are the Islamic oath and creed (shahada), daily prayers (salah), almsgiving (zakat), fasting (sawm) in the month of Ramadan, and a pilgrimage (hajj) to Mecca. Islamic law, sharia, touches on virtually every aspect of life, from banking and finance and welfare to men's and women's roles and the environment. The two main religious festivals are Eid al-Fitr and Eid al-Adha. The three holiest sites in Islam are Masjid al-Haram in Mecca, Prophet's Mosque in Medina, and al-Aqsa Mosque in Jerusalem.

Muhammad (c. 570 – 8 June 632 CE) was an Arab religious, military and political leader and the founder of Islam. According to Islam, he was a prophet who was divinely inspired to preach and confirm the monotheistic teachings of Adam, Noah, Abraham, Moses, Jesus, and other prophets. He is believed by Muslims to be the Seal of the Prophets, and along with the Quran, his teachings and normative examples form the basis for Islamic religious belief.

According to the traditional account, Muhammad was born in Mecca to the aristocratic Banu Hashim clan of the Quraysh. He was the son of Abdullah ibn Abd al-Muttalib and Amina bint Wahb. His father, Abdullah, the son of tribal leader Abd al-Muttalib ibn Hashim, died around the time Muhammad was born. His mother Amina died when he was six, leaving Muhammad an orphan. He was raised under the care of his grandfather, Abd al-Muttalib, and paternal uncle, Abu Talib. In later years, he would periodically seclude himself in a mountain cave named Hira for several nights of prayer. When he was 40, in c. 610, Muhammad reported being visited by Gabriel in the cave and receiving his first revelation from God. In 613, Muhammad started preaching these revelations publicly, proclaiming that "God is One", that complete "submission" (Islām) to God (Allāh) is the right way of life (dīn), and that he was a prophet and messenger of God, similar to other prophets in Islam.

The holy books are a number of religious scriptures that are regarded by Muslims as having valid divine significance, in that they were authored by God (Allah) through a variety of prophets and messengers, all of which predate the Quran. Among scriptures considered to be valid revelations, three that are named in the Quran are: the Tawrat (Arabic for Torah), received by prophets and messengers amongst the Israelites; the Zabur (Psalms), received by David; and the Injil (Arabic for the Gospel), received by Jesus. Additionally, the Quran mentions the Scrolls of Abraham and the Scrolls of Moses, as well as individual revelations and guidance to specific Messengers.

Muslims hold the Quran, as it was revealed to Muhammad, to be God's final revelation to mankind, and therefore a completion and confirmation of previous scriptures, such as the Bible. Despite the primacy that Muslims place upon the Quran in this context, belief in the validity of earlier Abrahamic scriptures is one of the six Islamic articles of faith. However, for most self-identified Muslims, the level of this belief is restricted by the concept of tahrif.

In Islam, Muhammad (Arabic: مُحَمَّد) is venerated as the Seal of the Prophets who transmitted the eternal word of God (Qur'ān) from the angel Gabriel (Jibrīl) to humans and jinn. Muslims believe that the Quran, the central religious text of Islam, was revealed to Muhammad by God, and that Muhammad was sent to guide people to Islam, which is believed not to be a separate religion, but the unaltered original faith of mankind (fiṭrah), and believed to have been shared by previous prophets including Adam, Abraham, Moses, and Jesus. The religious, social, and political tenets that Muhammad established with the Quran became the foundation of Islam and the Muslim world.

According to Muslim tradition, Muhammad was sent to the Arabic community to deliver them from their immorality. Receiving his first revelation at age 40 in a cave called Hira in Mecca, he started to preach the oneness of God in order to stamp out idolatry of pre-Islamic Arabia. This led to opposition by the Meccans, with Abu Lahab and Abu Jahl as the most famous enemies of Muhammad in Islamic tradition. This led to persecution of Muhammad and his Muslim followers who fled to Medina, an event known as the Hijrah, until Muhammad returned to fight the idolaters of Mecca, culminating in the semi-legendary Battle of Badr, conceived in Islamic tradition not only to be a battle between the Muslims and pre-Islamic polytheists, but also between the angels on Muhammad's side against the jinn and false deities siding with the Meccans. After victory, Muhammad is believed to have cleansed Arabia from polytheism and advised his followers to renounce idolatry for the sake of the unity of God.

In Islam, the exact date of Muhammad's first revelation is disputed, but it is generally believed by Muslims to have occurred in 610 AD. According to Islamic belief, during this time, Muhammad sought solitude after repeatedly experiencing transcendental dreams in which he was told of his upcoming responsibility as a messenger of God, prompting him to retreat to Jabal al-Nour near Mecca, where, while isolating at the Cave of Hira, he was visited by the angel Jibreel, who revealed to him the beginnings of what would become known as the Quran. Thus, at the age of 40, Muhammad's religious career as the "Seal of the Prophets" had begun.
