Not sure whether this kind of shallow article is useful. However, it seems wrong to link inline terms like w:Sunni directly to Wikipedia without warning. If someone is reading about these issues here, presumably, they do not need a whole scholarly discourse, but a very basic definition that lets them understand news items and other articles. They can always click through to the Wikipedia article for in-depth coverage if they feel it is necessary.
Please advise? If it's useful, then, others like Shia and Islam and sunnah and fiqh (one cannot understand Islamic law or sharia without understanding both concepts) can be given a similar shallow treatment. If it's not useful, then, do we link directly to Wikipedia where such concepts must be referenced? Or use extremely shallow articles like:
See en: wikipedia: Sunni ?
