Brelvis & Ahmedi were against Jihad and Deobandi were in favor of it. British used Ahmed Raza khan and Ahmad Qadian to run a campaign against the scholars of Deobandi and so call Wahabai campaign started. Anyone who didn’t follow Sufi Brelvis style was call Wahabi. There is a very good video on Youtube about the history of Brelvi and Deobandi split and ideology.
