At some point, Muhammad adopted the practice of meditating alone for several weeks every year in a cave on
Mount Hira near Mecca. Islamic belief holds that in one of his visits to Mount Hira in the year 610, 13 years before the
Hijra, the angel
Gabriel began communicating with and commanded Muhammad to recite the following verses of the 96th
Surah of the
Quran,
Al 'Alaq: Proclaim! (or read!) in the name of thy Lord and Cherisher, Who created- Created man, out of a (mere) clot of congealed blood: Proclaim! And thy Lord is Most Bountiful,- He Who taught (the use of) the pen,- Taught man that which he knew not. (Qur'an ) Most
Sunni traditions believe that upon receiving his first revelations Muhammad was deeply distressed, but the spirit moved closer and told him that he had been chosen as a messenger of God, and that Muhammad returned home and was consoled and reassured by Khadija and her
Christian cousin,
Waraqah ibn Nawfal.
Shiite Muslims maintain that Muhammad was neither surprised nor frightened at the appearance of Gabriel but rather welcomed him as if he had been expecting him. The initial revelation was followed by a pause of three years during which Muhammad gave himself up further to prayers and
spiritual practices. When the revelations resumed he was reassured and commanded to begin preaching: Your lord has not forsaken you nor does he hate [you] (Qur'an )According to
Welch, these revelations were accompanied by mysterious
seizures, and the reports are unlikely to have been forged by later Muslims.
Mission and early efforts Muhammad's early efforts in preaching the new faith focused on the preaching of a single ideal:
monotheism.
Surahs of the Quran believed to have been revealed during this period, known as the
Meccan surahs (), command Muhammad to proclaim and praise the name of
Allah, instruct him not to worship idols or associate other deities with Allah and to worship Him alone, Early converts to Islam included Muhammad's wife,
Khadija, his cousin
Ali, his adopted son
Zayd, his nursemaid
Umm Ayman, and his friend
Abu Bakr. Very few of the
Quraysh gave weight to Muhammad's message; most ignored it and a few mocked him. According to
Welch, early Qur'anic verses were not "based on a
dogmatic conception of
monotheism but on a strong general moral and religious appeal," further adding that the key themes of these
Meccan surahs include the
moral responsibility of man towards his creator: the resurrection of the dead, the Day of Judgement supplemented with vivid descriptions of the tortures in hell and pleasures in paradise, the wonders of nature and everyday life, the signs of God, and the proof of the existence of a greater power who will take into account the greed of people and their suppression of the poor. The foundations of early religious duties were also laid and included
belief in God, asking for forgiveness of sins, offering
frequent prayers, assisting others with emphasis on those in need, ejecting cheating and the love of wealth, chastity, and the prevention of
femicide which was prevalent in early
Arabia. Around 613, the Quran commanded Muhammad to "admonish your nearest kinsmen," initiating the phase of public preaching. One day, Muhammad climbed the
As Safa mountain, and called out the tribal chiefs. After receiving assurances that the chiefs, who reportedly never heard Muhammad tell lies, would believe him, he declared the
Oneness of God. Later Muhammad
organized dinners in which he conveyed and advocated the substance of his message. At these events, Muhammad met fierce opposition from one of his uncles,
Abu Lahab.
Opposition and persecution of early Muslims Conservative opposition arose to Muhammad's speeches. According to
Ibn Sa'd, the opposition in Mecca began with Muhammad delivering verses that "spoke shamefully of the idols [the Meccans] worshiped other than
[Allah] and mentioned the perdition of their fathers who died in disbelief." According to Watt, as Muhammad's followers gained traction in
Mecca, they posed a new, internal threat to the local tribes and the rulers of the city, whose wealth rested upon the annual pilgrimage to the Kaaba, the focal point of Meccan religious life, which Muhammad threatened to overthrow; his denunciation of the Meccan traditional religion was especially offensive to his own tribe, the Quraysh, as they were the guardians of the Ka'aba. Relations between Muhammad's Islamic faction and the other members of the
Quraysh rapidly deteriorated. Muhammad's open denunciation of the Meccan idols provoked hostile reactions, and he was mainly protected from physical harm for he belonged to the
Banu Hashim; injuring Muhammad threatened to open up a blood feud between the Banu Hashim and the rest of the Quraysh, undermining the legitimacy and morality of the tribal leaders, thus, the Quraysh were reluctant to hurt or kill Muhammad. Traditional Islamic accounts maintain that the Quraysh first taunted Muslims by interrupting their prayers. Western scholars have accepted records of persecution and ill-treatment of Muhammad's followers. Many of Muhammad's followers were harassed, assaulted and forced into exile—and two,
Yasir bin 'Amir and
Sumayya bint Khabbat, were tortured and killed. of Axum,
Ashamah al-Negashi (also spelled Najashi), rejecting the Meccans' demands of surrendering the Muslims in
Rashid ad-Din Sinan's World History. In 615, at a time of heightened violence against the Muslims, Muhammad arranged for his followers to emigrate to the
Kingdom of Aksum and found a small colony there under the protection of the Christian king,
al-Negashi.
Umar's acceptance of Islam and banishment of the Hashemites Sunni Muslims believe Muhammad prayed for the strengthening of the cause of Islam through the conversion of either
Umar ibn al-Khattab or
Amr ibn Hishām. Umar initially reacted to Muhammad's preaching by ardently opposing it. Angered by Muhammad's preaching which had led to divisions within Meccan society, he eventually decided to kill Muhammad, whom he held responsible for the divisions. While en route to assassinate Muhammad, Umar was informed of his sister's conversion to Islam. Approaching his sister's house, he heard her reciting the
Quran. Eventually considering the words beautiful and noble, Umar converted to Islam, making his conversion public instantly. Tempered by Umar's conversion, Muslims could now pray openly at the
Kaaba, as the pagans were reluctant to confront Umar, known for his forceful character. The banishment lasted for two or three years but eventually collapsed mainly because it was not achieving its purpose and sympathizers of the Hashemites within the Quraysh finally united to annul the agreement. ==Events leading up to the Hijra==
