Following Hadith and Sunna is idolization of the prophet Muhammad against his will, since he is a human like us who must not be idolized.1, 2, 3
God commands that the Quran alone be the only source of religious teaching, and accepting any other source equals setting up other gods beside God.1, 2, 3
God gave us all the words we need in the Quran, so we should not seek the words of Muhammad or anyone else.1
Hadith and Sunna are the necessary test separating true Muslims, who accept no source but the Quran, from false Muslims who are attracted to them.1, 2
Hadith and Sunna have nothing to do with the prophet Muhammad, and following them is flagrant disobedience of God and His final prophet.1, 2
Hadith fits the Quranic description of a book where one can find anything one wishes, unlike the one consistent source, the Quran.1
Hadiths are narrations of people who never saw the Prophet; the first Hadith book was written by Bukhary, born more than 200 years after Muhammad's death.1, 2
Muhammad did not know the future, so the many Hadiths narrating future events are personal predictions unrelated to the Quran.1, 2
Muhammad was forbidden from uttering any religious teachings besides the Quran, and his sole function was to deliver the whole Quran and nothing but the Quran.1, 2, 3, 4
Obeying the messenger means obeying the words of God he uttered, the Quran, since the Quran came through his mouth; obeying a Hadith is obeying its narrator, not the Prophet.1, 2, 3
Seeking religious instructions from Muhammad or any source besides God supports Satan's claim that God needs a partner.1
The criterion of divine revelation is perfect preservation, so the vastly corrupted Hadith and Sunna can never be divine revelation, and most Hadiths are false fabrications.1, 2
The language of Hadith is in fact extremely difficult, so it is false that Hadith is needed to explain a difficult Quran.1
The most authoritative Hadith books report that the Prophet forbade writing anything from him except the Quran, so Hadith followers disobey their own teachings.1, 2, 3
The Quran is the only true Hadith of Muhammad, delivered from his mouth directly to the revelation writers without mediators, and all other Hadiths are misleading fabrications.1, 2, 3
The true love of Muhammad is to recognize him as a human and uphold the Quran alone, and he disowns Hadith followers on the Day of Judgment.1, 2, 3
Victory is guaranteed for true believers, so today's defeated Muslims cannot be true Muslims, because they accepted Hadith and Sunna beside the Quran.1, 2, 3
While the Muslims upheld the Quran alone they led the world, and progressive deterioration began when Hadith and Sunna appeared in the third century AH.1, 2
