Islamic sacred texts
In Islam, there are two main sacred texts: the Quran (also spelled "Koran") and the Hadith (or Hadeeth). These books teach and illustrate Islamic beliefs, values, and practices. They are also important historical documents (especially the Quran), which tell the story of the origins of the Islamic faith.
The Quran is the most sacred text, as it is believed to be the literal word of God as revealed to Muhammad. The Hadith is a secondary text that records sayings of Muhammad and his followers. These two texts form the basis for all Islamic theology, practice and Sharia (Islamic law).
The Judeo-Christian Bible is also respected as revelations from the true God, but Muslims believe the Bible to have been corrupted in transmission and translation.
The word "Quran" means "recitation" in Arabic. This book is the sacred text of Islam and the highest authority in both religious and legal matters. Muslims believe the Quran to be a flawless record of the angel Gabriel's revelations to Muhammad from 610 until his death in 632 AD. It is also believed to be a perfect copy of a heavenly Qur'an that has existed eternally.
The word "Hadith" means "narrative" or "report" in Arabic. The book is a record of the words and deeds of the Muhammad, his family, and his companions. Although not regarded as the spoken Word of God like the Quran, Hadith is an important source of doctrine, law, and practice.
