CIRA International judge a sinner; the prophet Muhammad needed guidance from sin?

In answer to the video "Only Jesus is Sinless According to the Quran | Islamic Original Sin Dilemma"

Muhammad essentially raised himself, never worshiped the idols, never entertained the idea of doing so in the past 109:1-6. He would retreat away from the pagan environement to contemplate as some of his forefathers did, such as his great grand father the hanif, Hashim ibn Abd al-Manaf.

He would remain in such wandering perplexity until his prophetic call came unexpectedly. His firm stance against associating with God and polluting the Kaaba reached its peak then, despite his opponents' demands to compromise his message with their beliefs 68:9.

As vaguely alluded to by this youtuber, the Quran speaks of mankind's ingrained guidance, called the fitra 30:30. Although this device allows the possibility of avoiding the great moral harms and reasonably coming to believe in the most basic tenets of correct faith (monotheism and herefafter), even if one isnt exposed to any religion, it still cannot explain the complete and exact requirements of the Creator whom the upright person is convinced of.

Despite his awareness in those fundamental principles, the person therefore remains lost and ineffective in his search for an explicit guidance to know his obligations, how he should discharge them, how he should direct all possible aspects of his life in total subservience to God. Such person remains wandering in perplexity in search of the truth until he is shown the utlimate and precise manner in which his Creator is to be served

12:3,42:52,93:6-7"Did He not find you an orphan and gave you shelter? And found you lost and guided you?".

It is important to note here it doesnt speak of being lost from the straight path. One can be on the straight path all the while yearning and unsuccesfully looking for the best and ultimate way to progress on it, until it is shown explicitly. The difference between a prophet and philosopher is that the former, after seclusion and deep insight gets the truth and wisdom from God whereas the latter arrives to a glimpse of it or sometimes falls short of it by himself.

That condition the prophet was in, of seclusion and desperate seeking of the truth, as well as God's remedies to his concerns, inner questions and difficulties, is captured in sura duha and sharh. So, just as God, in answer to Ibrahim and Ismail's prayers, showed them the manner in which they and those after them should engage in worshipping Him 2:124-131, as was done to Adam who was taught the manner in which to invoke God and seek forgiveness 2:37,7:23,20:122 God showed the true rituals to Muhammad in answer to his spiritual quest, restoring them to their true form and purpose after they had been disfigured with time.

There is a lesson of humility, for a servant to reverently ask his master for the best way to please him, as Ibrahim asked his Lord, and to not be self-conceited in thinking that one knows best how to outwardly behave when addressing the Lord of creation just as one wouldnt disrespect the basic conduct to have when facing a mere wordly ruler. The form of a ritual is just as important as the sincerity in its execution.
