One of the most perplexing scenarios to non-Muslims and new Muslims alike is the division they may see between Shiites and Sunni Muslims. Some tend to become confused when they see that each group claims to be following the true Islam.
Many times, people see this division to be a major one, while the fact remains that Shiites only make up a mere 8 percent of the Muslim population, reaching even this figure after taking hold of certain important political regions in history. Not a division, one can confidently say that the Shiites are but one of the various splinter groups which left the pure teachings of traditional Islam. Sunnis, on the other hand, are not a splinter group, but merely name themselves as such to differentiate themselves from the Shiites and other deviant sects.
