Note the religious emphasis of the argument: they are trying to convince Muslims that Islamic loyalty demands they oppose the government. From the pro-jihad site Jihad Unspun, with thanks to the Constantinopolitan Irredentist:
Al-Qaida organization in the Land of the Two Rivers has issued a stern warning in response to those who take part in so-called Iraqi government while claiming to belong to Ahlu asunnah (the party that follows the teaching and practice of the messenger of Allah, Muhammad, peace be upon him.)
Here is their statement, uncut and uncensored, as translated by JUS….
Statement From Al-Qaida In Response To Those Who Take Part In The Government Of Cross Worshippers And Apostates And Claim To Belong To Ahlu Asunnah [People of the Tradition, i.e., orthodox Sunni Muslims]
In The Name Of Allah, Most Gracious, Most Merciful
Praise be to Allah, the Cherisher and Sustainer of the worlds. Final victory is on the side of the believers, and no aggression except on those who transgress all bounds. Peace and prayers be on the Imam of Mujahideen, our prophet, Muhammad, his family, and his companions.
News about attempts by some who claim to belong to Ahlu asunnah, to join the fake political process and share in power with the cross worshippers and apostates, have been circulating in various news media.
Those losers could not be farther from the sunnah of all prophets and the Imam of messengers, our prophet, Muhammad, (peace and prayers be upon him), who mandated the implementation of the Sharia (Islamic Laws of Allah), establishing Islam as the religion on land, and fighting those who reject the Lord of the Worlds.
Those claiming to belong to Ahlu asunnah, race to be in the arms of the Jews and Christians, for sake of positions, social status, and for love of this life over the hereafter. Not long ago, they were racing to harm the true sunnah and its party. Here they are again, doing what they do best, offering their allegiance and services to every tyrant, the curse of Allah be on them! How are they deluded (away from the truth)!
In their heart is a disease and deviation.
{Those in whose hearts is a disease- you see how eagerly they run about amongst them, saying: “we do fear lest a change of fortune bring us disaster.” Ah! Perhaps Allah will give you victory, or a decision from Him. Then will they regret of the thoughts which they secretly harbored in their hearts.}, [Qur’an] 5:52
We announce to the entire world that we are clear of you and whatever you worship besides Allah: we have rejected you, and there has arisen, between us and you, enmity and hatred forever, unless you believe in Allah and Him alone.
