Apostate prophet finds belief in reason; logic leads to God?

In answer to the video "Who (Really) Wrote The Quran?"

In order to know if one has the right approach to knowledge, one has to see whether the chosen approach is beneficial in terms of personal insight as well as insight into the surrounding world, what does this approach teach and where does it lead. What does it imply about truth, what truth is, and where truth can be found, what does it say about how to live one's every day life.

There are 3 main domains that the chosen approach must satisfactorily address; intellectually, morally, spiritually.

Intellectually; Why is the universe the way that it is and why are we able to learn and understand it? Why should man even probe the secrets of the universe.

Morally; how should life be lived and according to which virtues? In what circumstances is it better to be humble or proud, gentle or fierce, merciful or stern, patient or hasty? How does experience and the ability to overcome obstacles develop us in these virtues?

Spiritually: Why does mankind exist, more specifically why is my own life worth living? What point does my existence accomplish in the broader scheme of things?

Every single human being will eventually be confronted with these questions and will adopt some form of value system that attempts to address them. The only question to ask is whether or not the ideology to which they have committed can successfully and coherently address these dimensions of life in a manner that provides meaningful guidance.

Only Islam unifies all of life’s ethical, rational, and spiritual pursuits under the singular aim of attaining nearness to God, providing a firm foundation for true personal development in all spheres. The Quran speaks to human intuition in a way that renders reality meaningful, unravelling all of the paradoxical knots of confusion. Haqq/truth is used in the Quran to refer to what is real 10:32 but also to mean purpose 16:3 as well as rights and responsibility 30:47. Reality is therefore meaningful (makes intellectual sense) and purposeful (makes spiritual sense), and this is something that corresponds to human intuition. 

The Quranic discourse helps us make sense of what’s important and what’s relevant in our lives, what to focus on to achieve true spiritual, moral and intellectual growth. It does so by appealing to the existing knowledge of the fitrah.

Those who accepted the warners sent to them, firstly did it because they were not prejudiced but focused on the message that was being preached, noticing it agreed with elementary reason, their geneticly hardwired cognition of the higher realities, and their observation of the universe. That message was in addition transmitted by men who were obviously not deceitful charlatans motivated by any worldy pursuit.

These noble messengers knew that what they were comunicating could not be bought by any ammount of riches and favors, and were among the best of people in their nation

3:161,6:50,90,109,127,145,160,180,10:72,12:104,33:21,34:47,36:21,68:4,11:51,29,62"They said: O Salih! surely you were one amongst us in whom great expectations were placed before this; do you (now) forbid us from worshipping what our fathers worshipped? And as to that which you call us to, most surely we are in disquieting doubt".

Simple observation also shows that had these men been seeking illegitimate profits under the guise of prophethood, they would be surrounded by the affluent, yet the contrary can consistently be seen with every prophet. It was in fact one of the common reproaches which the aristocrats use to issue against them and the Quran particularily depicts how the prophet Nuh and his poor assemblies were the target of such scorn 11:27-30. Again, some very elementary points can be critically and objectively analyzed to assess the truthfulness of a person claiming prophethood.

None of these points have been meticulously and comprehensively documented on a scope even remotely comparable to Muhammad:
How was his life prior to the claim? What is his message? Then how did his life become after his claim? How consistent was it with the message and that of those prophets that preceded him? How much did he have to sacrifice in all aspects of life by upholding that message and what did it bring him? How did his successes and failures affect his thoughts, words and deeds? Finally what kind of fruits did his message produce in the lives of his contemporaries?
