Could you please provide me with the names of at least few books on tasawwuf/tareeqat/tazkiya mysticism that are based on the Holy Qur'an and Sunnah. I want to study such works as are very reasonable and logical. Which books are reasonable on this specific topic according to Farahi School?
The scholars of the Farahi School believe that Tasawwuf is a parallel religion and almost all the Sufis and their works teach wahdah al-shahood or wahdah al-wujood which have no basis in Islam. For detail please refer to Mr Ghamidi's article on Tasawwuf on www.al-mawrid.org.
I can suggest only one book that I know treats the issues of tazkiya. Please read Amin Ahsan Islahi's Tazkiya-e Nafs. I hope it will be of great help.
