Tanbihul Ghafilien is a very famous book written in Arabic. It deals with the rules and regulations for being a great and useful Muslim. It contains several sufism related problems. Due to its importance, the translator translated it into Urdu by the name of Rayda tus salihine. Its importance was also felt in English because this language lacks such useful book so Mufti A. H. Ilias rendered it into English. It is based on the Quran, Hadith, Sayings of the pious persons & sufi thoughts.
