The sacred scripture revealed from Allah Almighty to Beloved Prophet (Peace and blessings be upon him) through Angel Gabriel (Peace be upon him) over a period of 23 years.
It contains 114 chapters and approximately 6666 verses which explain the power of Allah, guidance for humanity and the historical events. This is the Holy Scripture for Muslims. This is not only the guidance for Muslims, but also for Non-Muslims too. When these verses were revealed, most of the companions memorized them and wrote down.
Later it was compiled as a book in the governing period of Uthman ibn Affan (May Allah be pleased with him). Therefore, it does not contain any words of human like in other religious scriptures. It contains purely words of Almighty Allah. Neither scribal errors nor scientific errors could be found in Al Quran.
