Does following Prophet Muhammad mean following Bukhari?

Say: "If you do love God, then follow me. God will then love you
and forgive your sins. God is Forgiver, Merciful."
3:31

The above Quranic words instruct us to follow the messenger. From this verse, the hadith advocates claim that we cannot follow Prophet Muhammad unless we follow his hadith and sunna. Is this the correct conclusion to be derived from 3:31? It can be shown that this contradicts two important Quranic verses:

FIRST
-

The only hadith to follow is the Quran which God calls the "Best Hadith":

These are God's revelations (Quran) that We recite to you truthfully.
In which hadith other than God and His revelations (Quran) do they believe? 45:6

Or have they not looked at the realm of the heavens and the earth and all things which God has created, and that their time may be drawing near? Which hadith after this (Quran), do they believe in? 7:185

God has brought down the Best Hadith; a Book (Quran) that is consistent in its frequent repetitions.
39:23

So in which hadith beside it (Quran) do they believe? 77:50

Or do you have some other book in which you are studying? 68:37

To claim that we must follow the hadith we find in the books of Bukhari and others clashes with all the above verses.

SECOND-
The only sunna authorised by God is the Sunna of God Himself:

Such was the Sunna of God for those who have passed on before. You will find that there is no substitute for the Sunna of God. 33:62

--------------------------------

If the Quran forbids us from following any hadith or sunna except those of God, then what does it mean to follow the messenger? To follow any person, we must first find out what this person followed, then follow suite.
The question is: How can we find out, with any degree of certainty, what a man who lived 1400 years ago followed? Since God commanded us to follow the messenger, it is only rational to expect God to provide us with the knowledge of what the messenger followed. Indeed, this information is given without ambiguity in the Quran in the following verses:

Say (O Muhammad), "I am not a novelty among other messengers, nor do I know what will happen to me or to you. I follow nothing other than what is revealed to me (Quran). I am no more than a clear warner." 46:9

When Our clear revelations are recited to them, those who do not hope to meet Us say, "Bring a Quran other than this, or replace it!" Say (O Muhammad), "It is not for me to replace it of my own accord. I only follow what is revealed to me (Quran). I fear, if I disobey my Lord, the punishment of a great Day." 10:15

The words in 46:9 and 10:15 assert the following:

1- Not only did Prophet Muhammad not follow anything other than the Quran, he was also commanded to proclaim to the people that he follows nothing other than the Quran. This command from God to Muhammad to make this proclamation is quite significant. Its importance is that it gives the believers the correct understanding of following the messenger and what the messenger followed.

2-
Since Muhammad followed the Quran and nothing else, it follows that he did not devise any religious rituals or regulations that are not in the Quran. Any claim to the contrary would mean that Muhammad disobeyed the command to follow the Quran and nothing else.

3-
Muhammad did not leave for his people a source of religion besides the Quran called his hadith and sunna. Any claim for the contrary once again would imply that Muhammad disobeyed the command in 46:9 and instructed his people to disobey such command! Prophet Muhammad, the obedient servant of God, is innocent of such lies attributed to him.

--------------------------------

Further confirmation of the correct meaning of following the messenger, is given in the following verses:

O people, a proof has come to you from your Lord, and We have brought down to you a clear light. 4:174

Those who follow the messenger, the gentile Prophet ......... Those who have believed in him, honoured him, supported him and followed the light (Quran) which was brought down with him; they are the successful ones. 7:157

The genuine believers who obey the words of God in the Quran will follow "the light" (Quran) that was brought down upon the messenger and no other source:

To conclude, all the above Quranic words confirm that to follow the messenger is to follow the Quran and nothing else.
