Muhammad and the Holy Quran
Muslims believe that during the month of Ramadan, the Holy Quran "was sent down from heaven, a guidance unto men, a declaration of direction, and a means of Salvation"
One day Muhammad
was sitting alone in the wilderness near Mecca when the Angel Gabriel appeared to him. The Angel commanded Muhammad to read. Muhammad responded "I am illiterate." The Angel Gabriel then taught Muhammad some verses from the Quran, which Muhammad memorized and appointed to prophethood
Islamic scholars believe that the first revelation occurred on the night of the 27th day of Ramadan. This night is called the Laylat-al-Qadr
(Night of Power). And according to the Quran, this is when God determines the course of the world for the following year.
The receiving of the Holy Quran is to the Muslims what the receiving of the Ten Commandments from Mount Sinai is to the Jews and Christians.
