The Almighty-Allah has commanded us to love the Family of the Holy Prophet (Peace Be upon Him) through the Holy Qur’an:

Say: “No reward do I ask of you for this except the love of those near offing.” Sureh Shura (42:23)

It is mentioned in the AHadith-Sharif:

Translation: You teach three things to your children: Love of the Holy Prophet (Peace Be upon Him), love of His family and the recitation of the Holy Quran. (Al Jame’ Ul Kabeer, Hadith No: 924; Jame’ Ul Ahadeeth, Hadith No: 961; Kanz Ul Ummal, Hadith No: 45409; Al Fath Ul Kabeer, Vol. 1, Pg No. 59)

The Almighty-Allah Most High says:

And The Almighty-Allah only wishes to remove all abomination from you, your Members of the Family, and to make you pure and spotless. Sureh Ahzab (33:33)

This verse of the Holy Quran establishes that the Prophet’s Family is protected from all kinds of defects, whether they are intellectual defects or defects of belief or any other kind of defect.

About the background of the revelation of this verse, Hazrat e Umme Salama (May The Almighty-Allah be well pleased with her) says:

Translation: This verse was revealed when the Holy Prophet (Peace Be upon Him) was present in my house. After this verse was revealed, the Holy Prophet (Peace Be Upon Him) summoned Hazrat e Fatima, Hazrat e Ali, Imam Hasan and Imam Hussain (May The Almighty-Allah  be well pleased with all of them). Then the Holy Prophet (Peace Be upon Him) said: This is my Family (Ahl al Bayt). Hazrat e Umme Salama (May The Almighty-Allah be well pleased with her) asked: O Prophet of The Almighty-Allah (Peace Be Upon Him): Am I not from the Ahl al Bayt? He (Peace Be upon Him) said: Certainly, you are also from my Ahl al Bayt. (Zujajatul Masabeeh, Vol. 5, Pg No. 316)
