what is the definition of Ahl ul Bayt

Maverick my friend, there is much to clarify to you but I will in this post just like to correct myself for the Hadith reference I gave earlier. The hadith was not recorded by Ismail Bukhari but Ahmed Ibn Hanbal. My apologies. Here is the correct reference:

The Prophet of Islam(pbuh&hf), said:

"Whosoever dies without recognizing the Imam of his time dies the death of the ignorance (Jahiliyyah)."

Ahmad b. Hanbal, al-Musnad
