ISLAMIC LAW
....Sharia is not optional; it is prescribed for believers (5:48).
Although Muslims as individuals often decide which parts to follow or ignore,
the Quran (33:36) says that it is not fitting for a believer to choose for themselves (i.e., disregard) any matter already decided by Allah.
Likewise, a government that limits God's Law in any way is an enemy of Allah and must be fought.
The establishment of Sharia is the fundamental objective of every Islamic terror group.
Once an Islamic state is in place, the Quran (9:29) and Sharia (o9.8) make it mandatory for Muslims to fight those Jews and Christians who will not convert or accept inferior status.
This reality is left out by proponents of Sharia in the West, who hide behind the cloak of religion and expose only the more benign personal rules (such as those dealing with prayer and hygiene).
This is to make it appear as if detractors are religious bigots whose real problem is intolerance for a different set of beliefs about God and worship.
