Wa alaikum assalaam bro. Welcome to the forums. Well 'Salafism' and 'wahhabism' are kinda the same thing. They are a group of people, mostly 'anti-madhab' thinking suddenly they are the ones more close to the 'salaf' (the pious predecessors) . It is a flawed concept due to lack of knowledge because if we start to examine the Madhabs we will understand the scholars of the Madhabs actually consist of the salaf. So the modern day 'salafism' is actually a misnomer.
