Looking for references for meat to be valid only if a muslim or ahlu kitab slaughters it

Where ever I read, be it here at stackexchange, or other websites or books, I cannot find any references that really support the claim that the one slaughters animals has to be a muslim (or from ahlu kitab, even here there is different of opinions). *I am sure there are some references somewhere in the Quran or in the Hadiths, because I cannot believe that so many people just claim this without any support.* But I am starting to get the feeling that this claim has developed by analogy (qiyas) because I cannot find any text proving otherwise yet. For instance, in this answer , there are no references at all: > The person who beheads the animal (either male or female ) must be Muslim . In this answer too: > The slaughterer must be either Muslim, Christian, or Jewish. I could go on and on quoting these claims without any references. I am looking for references for these claims. ---------- **EDIT**: I am looking for the basic proof of the argument. I.e the most basic argument with references to the Quran and Sunnah which supports the claim that the one slaughtering has to be muslim. For instance, if the verse **5:3** is the basic verse to prove that only meat slaughtered by muslims is halal, then it's enough with that verse, no need to add the verse 6:121 for instance. But if the scholars think it isn't enough proof with only 5:3, and the also add 6:121, then 5:3 + 6:121 would be the basic proof.
