That is, even if the satans wanted they could not impart truth and goodness to the people like a true teacher and reformer as the Quran does. Even if to deceive the people, they came out under the guise of a benefactor, their work would not be tree from blemishes, which would betray their ignorance and their hidden satanic nature. Similarly the life and the teachings of a person who poses to be a religious guide, under the influence and inspiration of satans, would inevitably reflect the wickedness of intention and design. Thus the satans can neither inspire others with piety and goodness, nor can those, who have any relation with the satans, become pious and righteous themselves. Then in addition to its high and noble teachings, the Quran is a lucid and eloquent Book, which contains the knowledge of reality. That is why it has over and over again put forward the challenge that human beings and jinns would never be able to produce a book like the Quran even if they collaborated with all their energies and capacities. Declare this: Even if human beings and jinns should cooperate with one another to bring forth a book like the Quran, they will never be able to bring anything like it, even though all of them help one another (Surah Bani Israil, Ayat 88).

Tell them: if what you say be true, then produce one Surah like this, and you may call to your assistance anyone you can other than Allah. (Surah Yunus, Ayat 38).
