Allah has promised to prevent and render ineffective any act of sabotage, destruction, alteration and change in His Book.

      This promise which is for the confidence of His Messenger and the assurance of Muslims, is:ِ

      ``It is We Who have sent down the Qurän, and We are its protectore.''

      Therefore the sacred book of Muslims, which is called Qurän, (THE READING) is not left unsupported or without a guard, that one may cover its body with mud; or blow out its beam and flame easily. The Book is similar to a sun that will never set. The eternal care of God will protect his own Book through all ages. This promise of protection has proved to be true, in the past 15 centuries. Unbelievers have always attacked the Glorious Qurän in different conditions, and with various means and weapons. They have done their best to corrupt or to undervalue it, or to negate or reduce its effect, but have always failed.

      As to the meaning of protection in this verse, there has been various views:ِ

1ِSome have taken the protection of God to mean against alterations and tampering with the Book; adding or omitting in the passages, which was done with the Bible.

2ِSome other commentators have said; God's protection is against opposition's misleading reasonings and logics. But all the above suggestions and views may apply as well and equally.

      Therefore all the Muslim commentators, scholars and doctors of the Law were, and are, of opinion that, not the least alteration, or perversion has ever been done in this Holy Book, after it has been revealed to our prophet; and that, the Book which is now in our hands is exactly the same as that which was in the hands of our prophet and his disciples. That heavy thing which our prophet frequently said:ِ ``I leave among you two heavy things; the Book of Allah, and my nearest kins.''

      All the great commentators and theologians of Islam, such as SHAIKH TOOSI, SAYYED MORTAZÄ, IBN BABUYEH, TABARSI, KÄSHIF-AL-GHETÄ, and MOHAGHIGH YAZDI, have laid a great stress upon the matter that there has been no change at all in the Holy Qurän; and each have their own reasoning for that.

      Even those few persons who have thought of some change in the book they talk of some verses to have been omitted or lost, and think of no change or perversion to have occured.

      Many books have been written during the past fifteen centuries, with accepted reasons proving that the present Qurän is exactly the same thing that our prophet left behind. In many important museums, throughout the world, there are many manuscripts of Qurän, which are written in the first and second centuries of Islam, and there also exists Qurän written by Hazrat Imam Ali (AS) and other saints that are exactly the same as the present Book.
