Assalamu alaykum The issue is not sufi vs salafee , it is salafee/laa-madhabi vs imam-e-araba. And specially Imam Abu Haneefa RA. Can they prove that the salafs were not on Quran and sunnah. The famous muhadditeen, mufassireen and pious scholars for 1300 years were not on Quran and Sunnah. Yes, if you compare the salafees with the false sufees, then surely the false sufees have to return, for that they need not turn to laa-madhabiyah. The sincere dawah of laa-madhabees is towards furoee masail (which were resolved and approved for 1300 years). It looks attractive because every muslim respects hadeeth and Quran, and that respected is NOT created by the laa-madhabees, it was already created in the minds of muslims by scholars of madhabs. The laa-madhabees are misusing that respect.
