In 2004 Interim constitution, Paul Bremer rejected Islam as a source of law in the Iraqi constitution [Link]but he didn’t mind using the text in the constitution [look below].
We already had some problems in Iraq because of the association of Islam in the constitution (i.e. marriage between different religions), using Islam as a source of law will create much more problems and I want to add that Islam is the not the perfect source because it’s violate the human rights declaration but this will be another post.
Lebanon is the only Arab country that doesn’t mention any religion as the official religion of the state and this will be our best choice.
1925
Article 13
Islam is the official religion of the State.
1990
Article 4
Islam is the religion of the state.
2004
Article 7
Islam is the official religion of the State and is to be considered a source of legislation. No law that contradicts the universally agreed tenets of Islam.
I say that from 1925 to 2004 the wording of this is always worse.
1925 (official religion) -> other can exist. Islam is for official ceremonies.
1990 (religion of the state) -> The state bow to the Islam
2004 the state bow to thew Islam and castrate its freedom to legislate.
Use the USA Constitution as a model.
If you want, name God as the giver of the rights no one, never, no matter the majority, have the right to take from you; but never spell out any religion name.
Spell out what the state can not do, and never must do.
Spell out that all rights are of the people, apart what is clearly given to the state from the people.
Spell out that the state and the government is from the people, by the people, for the people. And nothing else can give the government true legitimacy.
