The Heavenly Existence and the Love for the holy household of the Prophet
Not only the greatness of this great men, but rather the dignity and superiority of the entire honorable ones of this existing world is due to the love and connection with the holy infallible household of the holy Prophet (peace be upon them); even though the Angels who are nearer and closer to the threshold of Almighty Allah has gained their nobleness through the love of those great men. The holy Prophet (peace b upon him and his family) said:
Do the Angels obtain their nobleness except due to their love for Muhammad and Ali; and the acceptance of their guardianship?
This statement is very explicit and clear that the honor of the Angel is the outcome of their connection with the holy Prophet (peace be upon him and his progeny) and that of the commander of the faithful (peace be upon him).
The clear mirror of love is remembrance of Ali;
The incantation of the Angels is Nadi Ali (calling of Ali).
Even though this narration is concerning the Angels but there is another narration that is expressing this reality which shows that the entire inhabitants of the heaven which includes the Angels and other creatures are the lovers of the holy household of the Prophet (peace be upon them) and through that means they increase their nearness and closeness to Almighty Allah. Therefore as we’ve said earlier, love manifest the attributes of the beloved one before the lover and one of the attributes of the infallible household of the Prophet (peace be upon them) is their closeness and nearness to Almighty Allah. In this respect the entire heavenly creatures considered the love of these great men as the causes of their nearness and closeness to Almighty Allah.
We read in one of the supplication visitation of Jamiyah that was narrated from the holy household of the Prophet (peace be upon them) as follows:
The inhabitants of the heaven become closer to Almighty Allah through the means of your love and denial of your enemies.
It is the attributes of Ali that is not having ending;
There is no praise reciter of Ali except his God;
If you read his attributes till the day of resurrection;
It is not up to one alphabet out of his praise notebook.
