Faith Not Religions

Religions are retreating due to irrationality and atheism, not the solution. Others have much more civilized religions as compared to Muslims, and they need to. Most religions don't have clear authenticated history of origin like Islam. Life history of Islamic prophet is taken by followers as the most perfect example in every field of life--and in all situations. Muslims believe that not even the minutest change could ever be made or can be made in the Islamic doctrine, "Koran" due to God's guarantee of it's absolute truthfulness forever. Radical and moderate Muslims share such belief without any possible debate. Islamic Sharia is also equally divine for all Muslims because it is a part of the Islamic doctrine or the so-called 'perfect examples' set by Muhammad. Here is the problem; If Muslims follow what they believe as divine, all of them would definitely be radicals or, just Taliban-like, similar to ISIS. All of which is impractical in a civilized world. Why do they not practice what they believe as divine? Should they admit that changes are needed in the divine doctrine? Should they accept that there may be wrongdoings in the so-called perfect examples set by Islamic prophet? They should at least allow it to be questionable/debatable. I am sure and can easily establish that ISIS followed Islamic belief by the book.
I do not believe against universal human values, no matter who said it or where it was written. A loving heart is the only eligibility to have faith in God, those who don't qualify need not seek in books or prayers. Religions deny the divine right of every human to have faith in God, each one of them claiming to be an exclusive permit holder. Wisdom is ability and ignorance is the inability to acknowledge and accept the truth. True God/man-made religions.
