No, that is a huge miconception. Wahhabis are specifically the Saudi-brand of salafism. They tend to generally be pro-Saudi (which ISIS certainly isn’t). But it is true that Mohammed ibn Abdul Wahhab’s takfirism (excommunication) has influenced all terror groups. In academia, these groups are usually referred to as “takifirs”.

Meanwhile the Taliban is something all together. They aren’t salafi or wahhabi.
