This site really doesn’t make any sense. Muslims don’t even use these distinctions. Which isn’t very clever, since the site’s author wants to convert Muslims, but anyway.
The attempt is clear, trying to make Islamic movements and divisions analogous to Jewish ones (i.e., “conservative” and “liberal”) but there is no such thing as a conservative movement or sect in Islam, nor a liberal movement or sect, nor an innovator’s movement. The example given for innovators is Nation of Islam–which isn’t even part of Islam. It’s not even a “sect” of Islam really, it’s a completely different religion.
The article then tries to break up Muslims a different way–first of all is the Shi’a. Shi’a actually are a sect, but incorrect to say they’re focused on successors. Because the successors are the caliphs, who the Shi’a reject. The Shi’a rather are focused on Muhammad’s descendants and family as their authority.
Then he talks about “cultural Muslims.” The term is true but it doesn’t constitute a sect, just an ignorant portion of the population of Muslims that isn’t interested in studying religion much in the first place, and follows it as a matter of culture moreso than faith.
Sunni Islam has been maligned in this article, which says it holds “human traditions” as paramount. That’s not true, because the first source of authority for Sunnis is the Qur’an, and the second is the teachings of Muhammad to his companions.
The “inventors of new beliefs” technically aren’t Muslims at all, nor are so-called “modern Muslims” who try to change the beliefs of Islam.
Sufis can be Muslims or not–Sufism is more a movement that can be parallel to Islam or contradictory to it. There are Sufi Sunnis, for instance.
Kharijites were a sect, they broke off from the Muslims.
The Wahhabis are not a sect, more like a movement.
So overall that’s a pretty lame and unreliable article. It’s not going to teach you anything about “sects of Islam.” You’re better off learning about Islam, straight.
The Prophet Muhammad (saws) said his followers would split into a number of sects, that’s true, and that they would all be in the fire except one.
Which one?
Ahlus Sunnah wal Jama’ah.
That group is today known as “Sunnis.” They account for some 85% of Muslims today.
