Which among ulema deoband dissociate themselves from Ashraf Ali Thanvi and his works? Any names?
Entire publications houses are run after his name e.g. idara ashrafiya etc.
Such are the 'ulema deoband'
Note: Obviously NOTHING In Qur'an or Authentic ahadith is reported which can substantiate Thanvis 'recipe' to hold any grounds in Islamic scriptures.
Sufism is NOT Islam. Such are the consequences of blind following (Taqleed) of a person without seeking textual evidences for their claims.
