Bismillah irrahman irrahim

Say: "obey Allah and obey the Messenger, but if you turn away, he (Messenger Muhammad SAW) is only responsible for the duty placed on him (i.e. to convey Allahs Message) and you for that placed on you. If you obey him, you shall be on the right guidance. The Messengers duty is only to convey (the message) in a clear way (i.e. to preach in a plain way)."  
(  ÓæÑÉ ÇáäæÑ  , An-Noor, Chapter #24, Verse #54)

O you who believe! obey Allah and His Messenger, and turn not away from him (i.e. Messenger Muhammad SAW) while you are hearing.

It is one of basic islamic rule that in worship you are told of what to do because it is limited information while in general life you are told of what not to do as majority of things are permissible.

Holy Quran tells us about Sayyidina Muhammad sallallahu alyahi wassalam 68:4] And most surely you conform (yourself) to sublime morality. Another place Allah subhanahu wa ta'ala is saying, '3:31] Say: (O Muhammad) If you love Allah, then follow me, Allah will love you and forgive you your faults, and Allah is Forgiving, MercifuL. So if anybody is looking to please Allah subhanahu wa ta'ala you first look into Holy Quran to find out your answers. You get from Holy Quran that Sayyidina Muhammad sallallahu alyhi wassalam had a great character and to get salvation we need to follow him.

If you look at your life, one of the first things you would think about is prayer. Does Holy Quran tells you how to pray? It only tells you about position of Qiyyam, ruku' and sujud. What do you read in different position, you mention an ayaah of glorifying Allah subhanahu wa ta'ala been read in salah. Ok if we take that then it is our understanding, so next step, to be fair to yourself you should be judging your understanding. Read Holy Quran and try to understand it without the conext of history. Then read it with the right context and judge on how many places your understanding failed you. Apply the same ratio to performing of salah, do you really want to take that much chance with pleasing your Lord.

Now Allah subhanahu wa ta'ala says in Holy Quran, 'The Prophet has a higher claim on the believers than [they have on] their own selves." (33:6) and He says in another place, 'He who obeys the Messenger, has indeed obeyed Allah, but he who turns away, then We have not sent you as a watcher over them." (4:80) In this particular ayaah its not just follow/obey Allah subhanahu wa ta'ala and His Messenger, it says whoever follows the messenger has followed the Lord. We know there must have been a way in which Sayyidina Muhammad sallallahu alyhi wassalam prayed. So we look for the ways to find those resources and thats when the sunnah and ahadith come into practise.

Now if you are not sure whether you trust that whole process. Again you turn to Holy Quran, where we told that our early generations are better than the latter ones. Those early generations were the ones who understood the need of collecting ahadith and compiled them. [Shakir 56:10] And the foremost are the foremost,
[Shakir 56:11] These are they who are drawn nigh (to Allah),
[Shakir 56:12] In the gardens of bliss.
[Shakir 56:13] A numerous company from among the first,
[Shakir 56:14] And a few from among the latter.
Those ahadith and sunnah have a very sound chain of narrations, there are quite few ahadith collections. What you find in one collection, you would find the same hadith in another one with different chain. Fourteen centuries have produced thousands and thousands of scholars and every one of them believed and followed ahadith to follow religion properly. If you are doubting their base that mean you doubting what Allah subhanahu wa ta'ala is saying about this ummah that we are best of ummah raised.

Again in the end you have to see everything in context of relating matters, you cant pick one ayaah and prove it this way or the other. Hope this helps, you dont need to reply to these posts as you have said that you are short on time. I have just tried to explain to you the basics of my understandings.

wassalam

 QheQ, you have appeared after a long time. Perhaps your did not read my post in which it was clearly pointed out that the source of Islam is :

1. The Quran,   2. The Sunnah (the practice of the holy prophet)     3.  The Hadith (the sayings of the prophet  recorded in the books)

All these three are important in that order. hadith is very important for understanding the rligion of Islam. But you have now come back and you are saying that Quran should be taken as the source.. And Hadith should be kept as a valuable historic record. You are right that any Hadith which is not in accordance with Quran should not be accepted.
