Beginnings of the Quran

Muhammad began to pray alone in a cave named Hira on Mount Jabal al-Nour, near Mecca for several weeks every year.[59][60] Islamic tradition holds that during one of his visits to that cave, in the year 610 the angel Gabriel appeared to him and commanded Muhammad to recite verses that would be included in the Quran.[61] Consensus exists that the first Quranic words revealed were the beginning of Surah 96:1.[62] Muhammad was deeply distressed upon receiving his first revelations. After returning home, Muhammad was consoled and reassured by Khadijah and her Christian cousin, Waraqah ibn Nawfal.[63] Waraqah is variously described as an Ebionite priest (possibly of Mecca) or Nestorian. He also feared that others would dismiss his claims as being possessed.[39] Shi'a tradition states Muhammad was not surprised or frightened at Gabriel's appearance; rather he welcomed the angel, as if he was expected.[64] The initial revelation was followed by a three-year pause (a period known as fatra) during which Muhammad felt depressed and further gave himself to prayers and spiritual practices.[62] When the revelations resumed he was reassured and commanded to begin preaching: "Thy Guardian-Lord hath not forsaken thee, nor is He displeased."[65][66][67]A depiction of Muhammad receiving his first revelation from the angel Gabriel. From the manuscript Jami' al-tawarikh by Rashid-al-Din Hamadani, 1307, Ilkhanate period.
Sahih Bukhari narrates Muhammad describing his revelations as "sometimes it is (revealed) like the ringing of a bell". Aisha reported, "I saw the Prophet being inspired Divinely on a very cold day and noticed the sweat dropping from his forehead (as the Inspiration was over)".[68] According to Welch these descriptions may be considered genuine, since they are unlikely to have been forged by later Muslims.[15] Muhammad was confident that he could distinguish his own thoughts from these messages.[69] According to the Quran, one of the main roles of Muhammad is to warn the unbelievers of theireschatological punishment (Quran 38:70, Quran 6:19). Occasionally the Quran did not explicitly refer to Judgment day but provided examples from the history of extinct communities and warns Muhammad's contemporaries of similar calamities (Quran 41:13–16).[21] Muhammad did not only warn those who rejected God's revelation, but also dispensed good news for those who abandoned evil, listening to the divine words and serving God.[70] Muhammad's mission also involves preaching monotheism: The Quran commands Muhammad to proclaim and praise the name of his Lord and instructs him not to worship idols or associate other deities with God.[21][71]
The key themes of the early Quranic verses included the responsibility of man towards his creator; the resurrection of the dead, God's final judgment followed by vivid descriptions of the tortures in Hell and pleasures in Paradise, and the signs of God in all aspects of life. Religious duties required of the believers at this time were few: belief in God, asking for forgiveness of sins, offering frequent prayers, assisting others particularly those in need, rejecting cheating and the love of wealth (considered to be significant in the commercial life of Mecca), being chaste and not to kill newborn girls.[15]
