This anecdote is narrated by Allamah Tehrani(HA)

roza1 Whenever the name of one of the Masumeen(A) was mentioned, humility and etiquette would be apparent on Allamah(RA) face. 

He had particular reverence for Imam-e-Zamaan(AJ) (the 12th Holy Imam, May Allah hasten his re-appearance, Amen) – may we be sacrificed for him. 

He considered the position of the Prophet(A), Aimmah(A) and Hadhrat Siddiqa-ye-Kubra(A) (Sayyeda Fatima az-Zahra(A)) to be beyond description. 

He had a humble, reverential and pious manner in respect to them, considered their position and status to be celestial, and had an in-depth knowledge of their actions and history.
