what is the definition of Ahl ul Bayt

[Pagluu]

I understand the core issue very well my dear

In earliest sources ahlulbayt are always banu abdul muttalib , the blood relations of Prophet.
But later as Alid and Abbassid factions fell apart after the successful revolution against ummayyads each claimed itself to be ahlulbayt alone. And since 12er school is concerned with imams of Alid descent they only include the Five as ahlulbayt and no one else.
You are not confused as u selectively read history take what u like and leave the rest.Quite an easy position to take i must say !

may be then Imam Muslim and Tirmidhi didn’t know the “earliest sources” you are talking about.

You my friend are quite independent in your thinking. Its a waste of time until you prove something from the Holy Quran or a clear Hadith.
