This Is My Faith - Al-fatlawi, Ali - الصفحة ٤٤ - Glorifying Ahl Al-Bait (PBUT) is not Polytheism
(And when We said unto angels: Prostrate yourselves before Adam, they fell prostrate…)٢;٣٤.
Here the Almighty Allah illustrates that prostrating to Adam (PBUH) is not worshiping him but it is a form of honoring and veneration to the status of Adam (PBUH).
(And he place his parents on the dais and they fell down before him prostrate…)١٢;١٠٠.
The family of Yusuf (PBUH) prostrate before him is not for the sake of worshiping but again it is a way to honor him. This is exactly the Shi’a do when they bow or prostrate before the shrine of the Imams (PBUT); they do so only out of honor, respect and veneration to the Imams (PBUT) and not because they are gods or deities – Glorious Allah forbid!
Anwar: Great! This is a defeat to those slanderers who say we worship the Imams (PBUT).
Hasan: Yes, it is actually obvious for discerning people.
Anwar: I have a question here, as long as we are speaking about worshiping and worshippers.
Hasan: Yes, please!
