Sunni Islam or Sunnism is the largest branch of Islam. It is also the orthodox version of the religion. The word "Sunni" comes from the term sunnah, meaning the words and actions or example of Prophet Muhammad. Sunnis (which include the Salafis or "Wahhabis") account for up to 90% of all Muslims.
Sunnis, as with the Shi'ites, follow the Qur'an and Sunnah. They consider Sahih Muslim and Sahih Bukhari as the two most authentic hadiths, hence the term sahih which means "authentic" in Arabic. Within Sunni Islam, there are also four mainstream schools of fiqh (known as Madh'habs) which are accepted by one another.
