According to the Islamic belief system, a person association is directly with Allah and the Rasul of Allah (saw)! Nobody needs to prove their faith to anyone else!
One may choose to believe or not believe and he alone will face the consequence of his choice. The world is not a place of compulsion but an abode of invitation!
Nobody has the right to force anyone into believing in anything!
The following verse validates this:
There is no compulsion in (acceptance of) the religion (the system and order of Allah; sunnatullah)!
However, many who claim to be Muslim, do not comply with this verse. They attempt to enforce the Islamic way upon others via various manipulative means.
The biggest danger of religious compulsion is spawning hypocrites and impostors.
Whereas this world is a place of invitation and recommendation. One who has faith will fulfill the requisites of his faith according to the degree and strength of his faith, and one who does not have faith will live his life as he likes and face its consequence in the afterlife.
The consequence, in other words the natural outcome of one’s actions and deeds, will be faced in the afterlife within the system of Allah!
A significant portion of the population is egotistically inclined to control and rule the people around them. However, most of these people have not attained a status that actually enables them to be accepted by their community.
This being the case, they use religion to manipulate and channel people in the name of “Allah, the “Prophet” and the “Quran”!
If such people were examined psychoanalytically, it will be seen that in most cases these people are trying in effect to satisfy their own issues; striving to compensate for their own feelings of inadequacy and lack of self-confidence.
It is precisely these people and their followers who started the Medieval Inquisition of the Dark Ages to cast everyone into hell and who are relentlessly trying to continue this practice today.
Whereas the Quran says, “There is no compulsion in religion”!
Distinguished scholar Elmalili Hamdi Yazir explains this truth as the following:
This topic can be a book on its own, so let us suffice with this much for now and continue from where we had left off…
 Quran 2:256
