The verse of purification "Verily Allah only desires to ... " was revealed to the Prophet (s) in the house of his wife Umm Salama (may Allah be pleased with her); the Prophet called al-Hasan, al-Husayn, Fatima and ‘Ali, and he gathered them together and covered them with the mantle. Then he said, "O Allah, these are my Ahl al-Bayt, so keep away every impurity from the Ahl al-Bayt, and purify them with a perfect purification." Umm Salama said, "Am I with them, O Apostle of Allah?" The Prophet (s) said, "You stay in your place, and you are virtuous."
The beginning of verse 33:33 and subsequent statements are addressed to the wives of the Prophet (s) as is evident from the feminine pronouns used. However, in the verse of purification, the gender changes to the masculine or mixed gender. This also shows that it was an independent revelation addressed to different individuals.
Prophet Muhammad’s Legacy
“I am about to answer the call (of death). Verily, I leave behind two precious things (thaqalayn) amongst you: the Book of Allah and my Ahl alBayt. Verily, the two will never separate until they come back to me by the side of the Pond.”
This authentic hadith from the Prophet Muhammad (s) is narrated by over 30 of his Companions and recorded by a large number of Sunni scholars. Some of the famous sources for this hadith include:
alHakim alNaysaburi, alMustadrak `ala al-Sahihayn (Beirut), volume 3, pages 109-110, 148, and 533). He expressly states that the tradition is sahih in accordance with the criteria of alBukhari and Muslim; alDhahabi has confirmed his judgement

Didn't the Prophet (s) say “I leave behind the Book of God and my Sunnah” ?
This is a popular misconception. The fact is that there is no reliable basis for this statement attributed to the Prophet’s (s) Final Sermon. It is completely absent from any of the six Sihah books!! The version in Malik’s Muwatta’, Ibn Hisham’s Sirat Rasul Allah, and from him in al-Tabari’s Ta’rikh, all suffer from incomplete chains of narration with several links in the chain missing! The other versions that have a full chain of narration (isnad) - of which there are very few - all contain narrators that are unanimously considered to be highly unreliable by leading Sunni scholars of rijal. These remarkable facts can be confirmed by those interested in research by referring to the relevant books.
Clearly, no one is suggesting that the Sunnah of the Prophet (s) should not be followed. As stated before, the Prophet (s) wished for the Muslims to refer to his Ahl al-Bayt as a
