:If there are specific errors, you're welcome to edit them. However, be careful about adding "Islamic sources". For example, religious texts count as primary sources, and, as such, are generally not useful for verifying article content. Look tSimilarly, religious sources need to be examined and chosen carefully; they should ideally be from scholars of religion, not from religious organizations. Additionally, we need to be careful, especially when dealing with a figure like Ali, about whom there is obviously a lot of disagreement among Muslims, that we do not choose one "side" as being the "truth". But, feel free to recommend sources, and we can revert/discuss as needed; first, though, it will probably help for you to review WP:RS, which are Wikipedia's guidelines for reliable sources.
