May Allaah have mercy upon you. Know that the Religion is what came from Allaah, the Blessed and Most High. It is not something left to the intellect and opinions of men. Knowledge it is what comes from Allaah and His Messenger, so do not follow anything based upon your desires and so deviate away from the Religion and leave Islaam. There will be no excuse for you since Allaah's Messenger explained the Sunnah to his Ummah and made it clear to his Companions and they are the Jamaa'ah, and they are the Main Body (as-Sawaad ul-A'dham), and the Main Body is the truth and its followers.
So he who contradicts the Companions of Allaah's Messenger sallallahu alaihiwasallam in any of the affairs of the Religion, then he has fallen into disbelief.
