Comprehensive LegislationBesides the finesse of its rhetoric, the Qur'an constitutes the most comprehensive concept of Islam on the practical level, the shari'ah, or the laws and legislation. The Qur'an is comprehensive because it includes law, moral principles and the creed which every Muslim subscribes. The Islamic shari'ah is suitable not only for the Muslims, but for all mankind at all times. The Islamic law governs all human acts, public or private-duties towards Allah and duties towards man. Man-made laws are subject to alteration and are based on theories; whenever a new body of legislators assumes authority in a non-Muslim country or a new theory appears and appeals to its government, the laws are changed accordingly. The Divine laws, on the other hand, are unalterable and perpetual because the One Who made them is Everliving and Everlasting God. He is the Creator Who created mankind and ordained for them what suits them till the end of time. For this reason, the Qur'an, being the last revealed to the last of Prophets and Messengers. abrogates all previous Scriptures. Many prophesies in the Qur'an are fulfilled to the letter. Allah promised those who believe and did good deeds that He will surely make them successors on earth. The early Muslims ruled a vast land encompassing many countries in the world. The Qur'an foretold the victoryof the Romans over the Persians~. Allah says: «The Romans have been defeated, in the land nearby, and they after their defeat, will be victorious». A person who reads the Qur'an objectively shall realize that the prophesies in it are far removed from conjuncture or speculations. This is due to the fact that Who revealed them is the One who predecreed all events until the Day of Judgment. 2. The reference to this prophesy is found in surah #30 entitled 'Arrum' or the Romans. This refers to the battle which took place between the Persian and the Roman in 614 A.D. when the Roman werc defeated. Eight years after that. the Roman defeated the Persians, and the prophesy to the Qur'an was fulfilled to the letter.
