Misconception about Hadith

In Islam, there are two misconceptions among Muslims about sunnah of Prophet Mohamed (sw):

Misconception #1: "Following the sunnah is not obligatory but following the Quran is obligatory"--- This is wrong because God orders us to follow Prophet Mohamed in the Quran. In Islam, an obligatory action (fard) is something that God directly orders you to do in the Quran. For example, God says to pray in the Quran. Following Prophet Mohamed is an obligatory action (fard) in Islam.

Misconception #2: "Unlike the Quran, hadiths are word of men & that's why the authenticity of hadiths can't be trusted"--- this is wrong too. Muslims follow only those hadiths that are classified as sahih (authentic). For example, Sahih Bukhari & Sahih Muslim. A hadith must has an unbroken chain of narration & each narrator in that chain has to be credible in terms of his/her biography & scholarship. Islamic hadiths are more authentic than Christian Bible because we even don't even know the name of bible writers, let alone their biographies or information about their scholarships. For example, Christians don't know the last of name of Bible writer Mr. John, let alone is biography. A book's credibility is judged by the author's scholarship. Verbal testimony is considered valid in courts in even today's society. There's no rational logic behind not accepting a hadith that is based on verbal testimonies of credible Islamic scholars who passed down that hadith in writing from generation to generation. The real reason why some so called "Muslims" reject hadiths is not because hadiths are not authentic but they go against their worldview.
