The human beings with their limited knowledge cannot visualize the greatness of the Creator to any extent even after determining the indications and seeing events beyond one‘s imagination. Zenith of the knowledge acquired by the human beings is, that they should be able to recognize the blessings of Almighty, utilize them and thank Him in the real sense. The base of knowledge may expand to any extent and one may continue to acquire as much knowledge as one can do but must realize that he is standing on the ocean. Being Muslim, we believe that there are only too sources of knowledge, first is the Holy Quran and second is the pious life of the Holy Prophet .صلى الله عليه وسلمThe analysts claim that the Holy Quran contains 51000 types of knowledge and every moment of the life of last Prophet of Allah adds a new chapter to these horizons and thus our life. There are numerous types of knowledge. One of them is hidden knowledge known as spiritual knowledge and people of this school of thought are called mystics (Sufis) or Ahl-e-Tasawuf. Besides many other prevalent definitions of Tasawuf, it can be defined as “while living in the specific confines of the religion, consolidating the faith from the core of heart, regularly practicing it; eventually one starts realizing the sweet taste and soothing lights”. Depending on the truthfulness of any religion, the feelings of spiritualism would become pronounced. Thanks to Almighty, Quran is the most authentic and truthful book in the Universe and the life of the Prophet صلى الله عليه وسلمis the best example and beacon of light for the entire humanity. The Muslim who is lost in the oneness of Allah and fully focused in the slavery of the Prophet صلى الله عليه وسلمwould be enlightened with secret of this life and life thereafter.
