Muslims must obey the law of the land as anything to the contrary would mean that they are not obeying their Prophet or their religion.
Any country or government that guarantees religious freedom to followers of different faiths (not just Islam) must be owed loyalty. The Prophet Muhammad(sa) stressed this point when he said:
‘One who obeys his authority, obeys me. One who disobeys his authority, disobeys me.’ (Muslim)
In Islam obedience to the law of the land is a religious duty. The Qur’an commands Muslims to remain faithful to not only Allah and the Prophet Muhammad(sa), but also the authority they live under:
O ye who believe! obey Allah, and obey His Messenger and those who are in authority over you (
Ch.4: V.60).
I wont say true Muslims vs non true etc, but I will say Muslims that knows and studied their faith instead. U get easily influenced people in any faith that can be mislead.
