Salaam Akhi. Yes you are correct in the sense that according to Usul ul Bid'ah, driving a car is not bid'ah. It has to be ascribed to the deen for it to be a bid'ah. In terms of your question in post # 5, the extract I drew from the Orientalist work may provide some answers: "He forbade the use of stimulants as well as the practice of voluntary poverty. Lodge members were to eat and dress within the limits of religious law and, instead of depending on alms, were required to earn their living through work. No aids to contemplation, such as the processions, gyrations, and mutilations employed by Sufi dervishes, were permitted" - Seems like he was pretty anti-Bid'ah to me! I also encourage you look further into the "Salafi Sufism" (i.e. the 1st and 2nd stages as described by the Shaykh). Shaykh ul Islam Ibn Taymiyah (RA) didn't call Shaykh Abdul Qaadir Jilaani (RA) "Sayyiduna" for nothing. Ahmed ibn Hanbal (RA) didn't revere Bishr ibn Hafi (RA) for nothing. Don't let the recent deviations in Sufism make you reject the concept in it's entirety. E.g. In hadith, many fabrications crept in. That didn't lead the scholars to abandon hadith. They separated the truth from the baatil and stuck to it. So take what is in Sufism that is conformity with the Quran and Sunnah. Leave the rest.
