There is no such thing as "Sufi Islam". Tasawwuf is a branch of Islamic science, like the study of ahadith, tafsir, etc. Sufis are not a sect. It is not a "different approach" it's just another name for Tazikiyyah/Ihsan. Many deviants have usurped the title of Sufi, these are the people Ahlus Sunnah wal Jammah have always had a problem with. You have no idea what you are talking about, and are here yet again spreading misguidance.
