The earliest sūrahs (revealed during initial 13 years of prophethood, from 610 to 622 C.E known as Makkan period) call for strict monotheism, worship and obedience to Allah (One God), the moral and religious obedience in light of the coming Day of Judgment; the ones revealed later (10 years of Madni period from 622 to 632 C.E) generally provide directives for the creation of a social structure that will support the moral life called for by God. The Qur’an also provides detailed accounts of the joys of paradise for pious believers and the terrors of hell for sinners and disbelievers. The God who conveyed the revelations to Prophet Muhammad (peace be upon him), through archangel Gabriel, is the same God, worshiped by Abraham, Jacob, Moses, Jesus and all other prophets mentioned in Bible. The stern justice of God is emphasized in Qur’an along with frequent references to his mercy and compassion for the repentant believers.
The Qur’an demands absolute submission (Islam) to God: “Surely Allah’s religion is (Man’s) self surrender to Him (Islam).”(Qur’an;3:19).Both Qur’an and Traditions (Sunnah) of Prophet (peace be upon him) serve as the primary source of Islamic law (Shari’a). Qur’an is immutable in both form and content; the translations are just paraphrases to facilitate understanding of the actual scripture, in no way substitute to the original Arabic script (Appendix I). Qur’an is eternal guide for those who ponder. Allah says: “This Book (Al-Qur’an) which we have sent down to you (O Muhammad) is highly blessed, so that they may ponder upon its verses and the men of understanding may learn a lesson from it.”(Qur’an;38:29).
Some Qur’anic verses, draw the attention of humanity towards scientific phenomena, as His signs, related with Astronomy, Physics, Geography, Geology, Oceanology, Biology, Botany, Zoology, Medicine, Physiology, Embryology as well as General Science, mostly un known to humanity fourteen centuries ago, discovered recently proving miraculous nature of Qur’an as the word of God. The world’s leading authority on orientalism and Middle East, Princeton Professor Philip K. Hitti, in his book ‘Islam, a Way of Life’, writes; “The Koran is dictated (by Allah). Any quotation from the Koran can be introduced with ”saith Allah”. It is now for the mankind to make their own choice; weather to follow the distorted and corrupted ancient scriptures or the Last Testament, the message of divine guidance available in its pure form- The Qur’an! Backed up with practical demonstration of its application by Prophet Muhammad (peace be upon him) available in the form of written and oral record of Traditions (Hadith and Sunnah).
