The Islamic way of life is based on the teachings and laws found in the Qur’an and the example (Sunnah) of the Prophet Muhammad.
The Qur’an is the word of Allah and was revealed in potions to Muhammad, via the Angel Gabriel, over a twenty-three year period. Each portion was recorded in writing by his official scribes and memorized by thousands of his followers. After his death, the written collection was given to Abu Bark, the first caliph, who oversaw its collection into one volume.
The third caliph, Uthman, prepared several copies and sent them to different Muslim territories. Ever since that time, the same version has been used by Muslims. The wording, order, and language have never been altered in the slightest manner. No other book claiming to be a divine revelation can make this claim, and no one has ever been able to refute the claim of the Qur’an to complete authenticity
The Sunnah consists of the teachings, sayings, and actions of Prophet Muhammad. This information was meticulously reported and collected by his Companions. It is essentially an elaboration of the Qur’anic verses that shows how they are to be implemented in one’s daily life.
