Which Hadith other than GOD and His revelations do they believe? 45:6?

Verse 4 of the Sura The Women states that the source of Islam embodies no contradictions. By such a statement God confirms the truthfulness of the Quran as well as indicating how the book to constitute the source of religion should be. The very existence of the hadiths that contradict the Quran is proof that they cannot be considered as a source of Islam. Verse 15 Al Hijr 9 explicitly states that the Quran is a guarded and protected book.
