There is not a single verse in the entire Holy Quran in which Allah almighty has prescribed a worldly punishment for any religious offense
Two things become absolutely clear if one reads the Holy Quran :
1) Allah says that there is no compulsion in religion [2:256], It is a matter of free choice , No one is allowed to to force anyone in religious affairs. It is only for Allah to decide the punishment for religious offences
2) Disorderly conduct/Crimes that cause disturbance in the society (e.g theft, robbery, rebellion etc.) are punishable offenses
In any modern Secular state ;
1) Religion is a personal matter and not the business of the state
2) Disorderly conduct/Crimes that cause disturbance in the society are punishable offenses
So, a "State" based purely on Quranic teachings would be essentially "secular" where religion would be a "personal matter" and not the business of the state ...
