Of course u must follow the Hadith...the 'shahih' Hadith...

Quran only mentioned about Solat, without describing the way of performing it....
So, this is where the Hadith 'play' its role....And the reason why the prophet Muhammad S.A.W. 'taught' us of it....

Same with 'wudhu', and the 'tayammum'......Without refer to the Hadith, there's no way you could performs it the 'right' way....The truth is, if ya don't follow the hadith, its mean that u do not love Muhammad S.A.W., his teaching and his 'priceless' advices.....That will 'automatically' makes u differ from us....because we loved Muhammad S.A.W.....so following his teaching is the 'right' way....
