Apostate prophet disappointed; prophetic perfection?

In answer to the video "10 Reasons to Reject Islam"

This uswa hasana in no way implies that the prophet was a perfect creation. For example, After describing their outstanding moral and spiritual qualities, the Quran nevertheless asks the prophets to keep seeking istighfar/protection (from sins), for themselves and their followers too 47:19 and several prophets are quoted throughout the Quran asking for ghafr 30:24,35,71:28. This way the Quran teaches an important lesson; when the foremost among God's servants are denied any sense of complacency, then how far should regular believers be from harboring a feeling of perfect righteousness or prideful accomplishment in front of God

53:32"therefore do not attribute purity to your souls; He knows him best who guards (against evil)".

The believer should keep in mind that only God is perfection and as a demonstration of his understanding of such concept, should constantly seek God's forgiveness for any shortcoming as well as protection for future potential flaws and blemishes. This concept is pervasive throughout the Quran, starting with the single most repeated sura, sura fatiha. This type of spiritual humility is requested even from those that perform the most commendable deeds of the religion, so that they never fall into arrogance and self-righteousness 73:1-20. It was under this state of mind that the prophet implored his Lord for ghafr in this world, just as he will do in the hereafter 66:8. Some reports say he used to implore Allah for protection one hundred times every day, as he was commanded by the Quran itself. 

And he used to do so even after 48:2 was revealed telling him his past, present and future sins are forgiven. He did so out of humility and to set the standard of modesty in face of divine perfection 

"The Prophet used to offer night prayers till his feet became swollen. Somebody said, to him," "Allah has forgiven you, your faults of the past and those to follow." On that, he said, "Shouldn't I be a thankful slave of Allah?" 

No human, no matter how close to Allah in terms of revelational experience, will ever be faultless. This verse 48:2 does not say what type of sin, intentional or not, major or minor, was commited by the prophet. No indication of major sins, let alone intentional, are found concerning the prophet, anywhere in the hadith corpus or the Quran. Yet we find the Quran reproaching him even the slightest unfitting action for a man of his standing, actions which none would find problematic.

This is the etiquette that Islam has taught to man. 

This is the etiquette that Islam has taught to man. No matter how selflessly one might have exherted himself to please the Creator, one should never entertain the thought that he has fulfilled the right his Lord had on him wholly, the Sustainer who maintains him and the universe at each instant. Rather he should always think that he has not been able to fulfill what was required of him. This reveals an important point, something the prophets have always been aware of as seen in their constant prayers for forgiveness and protection, the inherent imperfection of humans, their shortcomings in the face of divine perfection. One should therefore never feel self-righteous or self-sufficient in any endeavour. The prophet said 

"All the sons of Adam make mistakes/khatta'in, but the best of those who commit mistakes are those who are given to repentance".

When a prophet of God, the last human capable of willfully sinning, asks for God's mercy not even following a sin, but out of fear of not performing an act of worship to its full extent, then how much more so should the regular believer be conscious of his shortcomings in regards to God?

This is the characteristic of the men of God, who never become complacent and arrogant, whether in their duties towards fellow men or towards God, especially so when they reach the climax of their power and glory and that before that point they were constant and steadfast upon the straight path regardless of their ordeals. Success instead causes them increase in spirituality and far sightedness in their dealings with men and their duties towards God. The prophet, and the Muslims through him, is told to do the following, after seeing the unfolding of the prophecy of entire victory

110:3"Then celebrate the praise of your Lord, and ask His forgiveness; surely He is oft-returning (to mercy)".

In addition to teaching man spiritual humbleness, this also conveys the idea that should one attain some victory, it should not lead to pride and vanity, but to remembrence of God and gratitude, as well as seeking ghafr/covering, protection from sins. Even if the prophecy proved true in the days of Muhammad, and even more so today as Islam is still spreading worldwide, a believer shouldnt be boastful about it as many Muslims usually are when speaking of the spread and success of their religion.

The prophet was therefore certainly not "uswa hasana" in how he ate (with the right hand because the left was used for relieving in cleaning oneself after), slept or saw the nature around him. Anyone is free to imitate his lifestyle and adopt his worldviews as found in extra Quranic writings, if one finds any personal benefits in doing so but that isn't a religious requirement nor relevant to it, and that is explicitly stated in the Quran itself.

With that in mind, when the prophet made deductions as related in the ahadith, pertaining to his natural environement, general causality and basic observation of certain phenomenon, it is only expected from him that they would fit what the ancients of his time would find "plausible". These views however, right or wrong, no matter how extraordinary they might seem in light of our current knowledge, have no bearing on the Quran itself, which is again, pledged to be fully protected.

It would have been interesting to have had written records of how the previous prophets saw the world, as we have with Muhammad, and see who among them held the most "unscientific" personal views.
