The Qur’an is the last revealed word of God and the basic source of Islamic teachings and laws. It deals with the foundations of creeds,
morality, the history of humanity, worship, knowledge, wisdom, the relationship of God to man and man to God, and all aspects of interpersonal relationships. Its comprehensive teachings are meant to be used to construct sound systems of social justice, economics, politics, legislation, junsprudence, law, and international relations, and represent important sections of the Qur’an.
Muhammad (PBUH) could not read or write. This did not represent an obstacle, for the Qur’an was committed to memory and writing by his followers during his lifetime and under his supervision. The original and complete text of the Qur’an is available to everybody in Arabic, the language in which it was revealed. Translations of the meaning into many languages are widely used. The hadith, a term which covers the literature dealing with the Prophet’s teachings, sayings, and actions, was reported and collected with great care by his devoted companions. Its main function is to explain and elaborate the Qur’anic verses.
