Assalam Alaikam Rahmatullah Wabaraktu,

But what some fail to learn is the term Taghut, which is shirk as well, which is implementing a Law other than the law of Allah swt. Which means, if you rule by democracy, socialism any system that is not Sharia, then you are committing Shirk.

And any mumeen must understand, for one to put forth a claim, he must provide evidence. Therefore,

Allah swt says in numerous ayahs:

Verily, We did send down the Taurāt (Torah) [to Mûsa (Moses)], therein was guidance and light, by which the Prophets, who submitted themselves to Allāh's Will, judged the Jews. And the rabbis and the priests [too judged the Jews by the Taurāt (Torah) after those Prophets] for to them was entrusted the protection of Allāh's Book, and they were witnesses thereto. Therefore fear not men but fear Me (O Jews) and sell not My Verses for a miserable price. And whosoever does not judge by what Allāh has revealed, such are the Kāfirûn (i.e. disbelievers - of a lesser degree as they do not act on Allāh's Laws). (Al-Ma'idah 5:44)

Let the people of the Injeel (Gospel) judge by what Allāh has revealed therein. And whosoever does not judge by what Allāh has revealed (then) such (people) are the Fāsiqûn (the rebellious i.e. disobedient (of a lesser degree) to Allāh. (Al-Ma'idah 5:47)

And We ordained therein for them: "Life for life, eye for eye, nose for nose, ear for ear, tooth for tooth, and wounds equal for equal." But if anyone remits the retaliation by way of charity, it shall be for him an expiation. And whosoever does not judge by that which Allāh has revealed, such are the Zālimûn (polytheists and wrong­doers - of a lesser degree). (Al-Ma'idah 5:45)

Had the muslims understood and contemplated on these Ayah, there would be no border lines...

Assalam Alaikam Rahmatullah Wabaraktu
