Oceanmen, I'm not sure the Kalama Sutta is particularly appropriate, particularly as the "praised by the wise" seems to promote the opposite idea to which I think you are trying to promote. What I mean is, I think you are saying one should learn Arabic and study the Qu'ran in its original language yourself before passing judgement rather than trusting someone else's opinion, whereas the Kalama Sutta seems to imply those who are "wise" can be trusted. The question, I suppose, is how one would define what "wise" is. I'm sure this is covered extensively in the Canon (I can think of a few places within the Dhammapada, for example, where distinction between "fools" and "the wise" are made).
Anyway, time for work for me (I'm working a day shift for a change!!!). I recommend you read the translators notes about the Kalama Sutta on accesstoinsight
