 Sunnis, by contrast, recognize the "Hadith al-Thaqalayn" as "sahih" but see it as mandating respectful obedience to members of the "Ahl al-Bayt", rather than pertaining to succession.The hadith of the Quran and Sunnah appears in the "Muwatta Imam Malik", often identified as one of the six most authentic books of hadith ("Kutub al-Sittah") in the Sunni tradition.Versions of this hadith (with slight variations) are cited in many Sunni collections.
