Laws related to the "State" ??
There is no concept of a state/country (local or global) in the Holy Quran and the concept of "State", as we understand it today, just like modern secularism, is a (recent) western concept
The Holy Quran does not prescribe any worldly punishment for any Religious offence
There are only four offences for which a specified punishment is stipulated in the Quran , namely adultery, theft, slanderous accusation and highway robbery .... Now if one were to review the whole theory of these hudud from a strictly Quranic perspective, the hudud can no longer be seen as mandatory and fixed penalties ....
The four Quranic verses on hudud consist basically of two provisions each, one specifying the offence and its punishment, and the other that provides for reformation and repentance. There is no expatiation beyond these terms. The question that arises is that the fiqh blueprint on hudud has essentially ignored the latter portion of the text. Only the penalties were adopted but no provision was made to implement or contextualise the repentance (tawbah) and reformation (islah) aspects of the hudud. A structure of penalties, indeed a penal system, was thus envisaged that provide virtually no space for an educational and reformative exercise - presumably because of the shortcomings of the pre-modern system of criminal justice .
Modern criminal law and jurisprudence (like Quran) also advise a restrictive approach to punishments. Two things become absolutely clear if one reads 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 (in the after life)
2) Crimes that cause disturbance in the society (theft , robbery etc.) are punishable offenses
In any modern Secular state ;
1) Religion is a personal matter and not the business of the state
2) Crimes that cause disturbance in the society are punishable offenses
So, a "state" based on Quranic teachings would be "secular" (in essence)!! After all, Muslim Philosophers like Ibn e Rushd (d.1198) are considered "founding father of modern secular thought" in western Europe ... Secularism is not as "western" as Mullahs will have us believe ...
