just google " arabic word for a god" and you get ilah. Allah is the "title" used in Islam for a SPECIFIC deity, which is not the same as the Jewish and Christian one.
The wiki link is not a TRANSLATION of the shahadda, it is the writers interpretation.
Have a look at the verse you quoted which uses the word ilah:
Please look it up here:
http://www.openburhan.net/" onclick="window.open(this.href);return false;
it is a MUSLIM site showing many translations together as well as the Arabic.
All say more or less this:
You left the word untranslated, as if it was a difficult word, it is a very simple word.Then seest thou such a one as takes as his god his own vain desire?
And then you quote the Qur'an to suggest what I told you is inaccurate? We all know what Muslims say about pagans Jews and Christians, that is not the question.
Can you point to and ORIGINAL Christian or Jewish text that even mentions "Allah"?
No, you can't because there is none. So how can you then suggest that Christians say "Christ is Allah"? Christians do not say that. Ask any Christian what they believe in, and Allah does not feature in the answer at all. Even if "Allah" is mentioned, because of much later language conventions in some countries, it is nothing like the Allah of Mohammed. Do Jews say "Allah's hands are chained"? I never heard any of them suggest any such thing.
In fact, you find neither Jews nor Christians as a rule spend a lot of time discussing other religions. It is only Islam which has a big focus on other people. Insecurity, perhaps?
What are these verses for, garudaman? Who are they talking to? The answer is they are for MUSLIMS. They are trying to explain to them, why, from Mohammed's point of view, other religions are false. They do this with very poor understanding what other religions are really all about.
In some ways the argument against Christians says rather a lot about Islam. Allah can destroy Jesus. Therefore he is more important and more powerful. Is importance measured in how easily you can kill people? That is the argument of the mafia don.
Mohammed really had no understanding about Christianity at all and his knowledge of Judaism was little better.
