Quran Karim is the holy book of Islam. It contains the basic principles of Islam, and the teachings and the explanations of the Quran, which are the primary source of religious knowledge for Muslims.

The Quran was revealed to the Prophet Muhammad, who lived in the city of Mecca. He was the leader of a group of people called the "Arabs", and he had a community in Medina, which is located in the province of Saudi Arabia, near the city of Taif. The Quran is the only book that has been preserved from the time of the Prophet. It is the last and the greatest book that has ever been written, and it contains the law, the guidance, and the wisdom that mankind needs.
