Imam explains the matter in through his theological works as following:
According to Imam, this is an evident fact that we respect great people and those older in age.
This is also true that people respect the wealthy and powerful persons, and rulers and kings, since they are recognized as great.
Can their greatness be matched with the grandeur and magnificence of that King of kings, in Whose kingdom this world of us is merely a particle of dust.
He is the Creator and King of this vast cosmos, whose infiniteness cannot be measured or even conceived by human intellect.
