Muhammad (peace be upon him) was born in Makkah in the year 570. Since his father died before his birth and his mother died shortly thereafter, he was raised by his uncle who was from the respected tribe of Quraysh. He was raised illiterate, unable to read or write, and remained so till his death. His people, before his mission as a prophet, were ignorant of science and most of them were illiterate. As he grew up, he became known to be truthful, honest, trustworthy, generous, and sincere. He was so trustworthy that they called him the Trustworthy. Muhammad (peace be upon him) was very religious, and he had long detested the decadence and idolatry of his society.

At the age of forty, Muhammad (peace be upon him) received his first revelation from God through the Angel Gabriel. The revelations continued for twenty-three years, and they are collectively known as the Quran.

As soon as he began to recite the Quran and to preach the truth which God had revealed to him, he and his small group of followers suffered persecution from unbelievers. The persecution grew so fierce that in the year 622 God gave them the command to emigrate. This emigration from Makkah to the city of Madinah, some 260 miles to the north, marks the beginning of the Muslim calendar.
