Such improvident who lack forethought...
Such improvident who lack forethought, by such false ideas strike upon the validity of the most important Divine Book, in contrast to the belief of all the learned Muslims of different sects, which maintain that the Holy Qur’an is unaltered for the least word. These unwise friends, water the mills of the enemy through their ignorance and bring into question the book which is sent by Allah, and has been promised to be guarded by Allah.
If we carefully study the ways that the book was revealed to the prophet and collected by the chosen scribes, and how it was guarded, written, memorized and recited by so many firm and true believers, no doubt remains as to any alteration or the change of even an epsilon in the whole work.
On the other hand, of the imaginary or assumed Holy Qur’an with some alteration, not ever a copy exists anywhere, or in any hand, so as to differ with the famous Holy Qur’an which all the Muslims hold as their sacred divine book. Today the Holy Qur’an is found in every house and in every library.
Even those Qur’ans written several hundred years ago are kept in our museums and those in the non-Islamic countries too, and no one can find the least differences in all the existing Qur’ans throughout the world. Today the roads to investigations are open to all, and anyone who doubts, may look for it himself and make sure that the Holy Qur’an has not been altered in the least. "So announce glad tidings to My Servants, to those who listen to My precepts, and follow what is the best in them.
Those are the ones that Allah has guided and those are endued with understanding." Holy Qur’an, 39:17 Today in our religious schools the knowledge of the Holy Qur’an is extensively taught, and one of the most important of our lessons in this field is the inability to change the Holy Qur’an. Holy Qur’an and the Spiritual And Physical Needs of Humans We believe that whatever is needed in spiritual and physical dimensions of man is fundamentally found in the Holy Qur’an.
