وَمَنْ أَقَرَّ بِلِسَانِهِ وَلَمْ يُصَدِّقْ بِقَلْبِهِ كَالْمُنَافِقِ
One who professes with the tongue without inward assent is like a hypocrite.
In doctrinal hypocrisy, outward profession coexists with inner rejection. Worldly dealings may be based on what is outwardly shown, but an insincere profession does not conceal inner rejection from Allah.
Consequently: The public declaration of faith is significant evidence for applying outward rulings. It does not authorize others to claim certain access to someone's hidden intentions or hypocrisy.
