Perfect Source of Guidance
Quran is the last book of Allah revealed on the last prophet Mohammad (PBUH) through angel (Gabriel) in the time period of 23 years for the guidance of mankind. Uniqueness of Quran over previous books of Almighty Allah is that this book is not specific for a particular nation or a group of people it is for all human beings present on earth without any discrimination and no one is able to change a single word of Quran, it is still present in that condition in which it has revealed.
