This essay, written in the immediate aftermath of the failed New York City bomb attempt [1], will examine some of the theological implications of Muslims violating civilian immunity. I have written elsewhere why attacks against innocent civilians are in opposition to fundamental teachings of Islam. Unfortunately, there are some Muslim ideologues that sanction such actions and a growing number of Muslim civilians and noncombatants are being killed by their coreligionists, in Iraq, Afghanistan [2], and elsewhere. For these reasons, the argument that follows is more than merely hypothetical.

Every Muslim who is concerned for the future of his or her faith and the future of the prophetic legacy in the world is morally obliged to work in whatever capacity he or she can to stop attacks that target innocent civilians by any party –Muslims or members of other communities. The basis for this moral obligation is powerfully stated by Imam Razi in his commentary on (5:32). He mentions:

If all of humanity knew that a single individual intends to exterminate them they would undoubtedly try their utmost to prevent him from obtaining his objective. Likewise, if they knew that he intends to kill a single person then their seriousness and exertion in trying to deter him from killing that person should be just as great as it would be in preventing their own mass murder. [12]
هو أن جميع الناس لو علموا من إنسان واحد أنه يقصد قتلهم بأجمعهم فلا شك أنهم يدفعونه دفعا لا يمكنه تحصيل مقصوده فكذلك إذا علموا منه أنه يقصد قتل إنسان واحد معين يجب أن يكون جدهم واجتهادهم في منعه عن قتل ذلك الإنسان مثل جدهم واجتهادهم في الصورة الأولى


The reason for this is that the life of a single innocent person has the sanctity of the lives of all humanity. This is an ideal we cannot let die. If we allow it to die who will revive it? Human history has shown how quickly we can begin a free fall into murderous madness once we have entered upon the path that justifies murdering innocent civilians and other noncombatants. If the American military and the warmongering interests supporting it are guilty in this regard we condemn them in the strongest terms, and if our fellow Muslims are guilty we must likewise condemn them.

The only difference between the two cases is that when the American military kills innocent civilians it is violating principles of human rights and worldly conventions, which, as we have seen with the current arguments justifying torture, are subject to change or being discarded altogether. When Muslims do it, we are betraying our faith and the legacy of the Prophets, peace upon them, who have left us a wealth of timeless, enduring wisdom.
