Al-Qur'an is the of All Truth

Became my conviction that the Holy Qur'an is perfect in his Teachings and completely contains all the truth that is as stated in the word of God Almighty that:

"Have we sent down to thee the book to explain all things". (S.16 An-Nahl: 90)
and the verse:

"There is no something that we omitted in this book". (S.6 Al-Anaam: 39).

But I also think that it is not the function of any scholar or Maulvi to express and declare the religious matters of the Qur'an. This is a function of the people who specifically had been helped by divine revelation as part of the semi Prophet Hood or purity. They are not the recipient of revelation, was not competent enough to bring insights into the Qur'an. The only way for them is to accept all the Teachings that have been received from generation to generation without trying to Interpret the Qur'an.

Those who obtain enlightenment in sacred revelation Nur was among those who are sanctified. To them this was God s.w.t. from time to time opened the pearls of wisdom hidden in the Qur'an, and explain to them that the Messenger of God's Presence there is no increase whatever adds his own opinions in the Qur'an, Hadith suggests that in addition to the valid only bring the details of the principles and guidance in the Qur'an. With these insights Reveal the miracle of the Qur'an so real to them flushed and the truth of the verses which according to God Almighty "There is no something that we omitted in this book". Became clear to them. (Al-Haq, Mubahisa Ludhiana, Qadian, 1903, now printed in Ruhani Khazain, vol .. 4, p. 80-81, London, 1984).

Meaning than the verse:

"He who has sent in the middle of the illiterate nation a Messenger from among themselves, who read to them signs of his, purify them and teach them the Book and Wisdom". (S.62 Al-Jumuah: 3)
This is to show that the Holy Koran has two great purposes for which it has sent the Prophet Hadzrat The first is the wisdom of wisdom of the Qur'an that is related to insight and wisdom pearls they contain. The second is the influence of the Koran in Purifying the mind.
Preservation of the Qur'an not only mean maintaining the integrity of the text, because these functions have also been carried out by the Jews and Christians associated with the sacred books of their long ago, such that the pressure of living letters (vowel) of The Torah was their attention. What is meant by preservation of the Quran is not just only text but also maintain the benefits and maintain the influence of the Book and this can be done in line with the management of the Divine if from time to time are always brought in representatives from the Prophet Hadzrat where they are obtained thanks to the apostolate as a reflection of his form of reflection. This is indicated in verse:

"God has promised to those among you who believe and do deeds of righteousness bermuat, that He would have made them the caliphs in the earth as He has made the caliphs of the people before them, and He will affirm for them their religion, that He has ridhoi for them and surely He will give them security and peace as a substitute after the terror seized them. They will worship Me and they will not associate anything with Me. And Whoever disbelieved after this, they are the people who are ungodly " . (S.24 An-Nur: 56).
This verse explains the meaning of other verses is:

"Verily, We it is Who sent down this warning and We is as the keeper". (S.15 Al-Hijr: 10)
as an answer to the question of how the Koran would be maintained. God Almighty has said that from time to time he would send the Heir to the Prophet Presence
