I want to know the answer to the following question:
Whose family are the Ahl al-Bayt a part of?
All the background I'm provided with is that "These Imams have the role of providing commentary and interpretation of the Quran as well as guidance to their tariqa followers as is the case of the living Imams of the Nizari Ismaili tariqah.". Is that enough to answer the question?
Answer: no
