This worldly knowledge is not called (Real) Knowledge. It is worldly knowledge. The scriptural knowledge is known as the instrumental knowledge. The knowledge about the goal [to attain Pure Soul] is Real ‘Knowledge’. Scriptures themselves are the instruments and the knowledge within the scriptures is also an instrument; whereas, the ‘knowledge’ of the Self is the goal [to attain Pure Soul]!

- Dada Bhagwan

In a proper Islamic University, fard 'ain knowledge which represents the permanent intellectual and spiritual needs of the human soul--should form the core curriculum, and should be made obligatory to all students. Fard kifayah knowledge--reflecting societal needs and global trends--is not obligatory to all, but must be mastered by and adequate number of Muslims to ensure the proper development of the Community and to safeguard its proper place in world affairs. The fard 'ain knowledge shall include knowledge of the traditional Islamic sciences such as the Arabic language, metaphysics, the Qur'an and Hadith, ethics, the shari'ah sciences, and the history of Islam. Consonant with our position that these fard 'ain sciences are not static but dynamic, they should be continuously studied, analyzed, and applied in relation to the fard kifayah sciences; i.e. the fields of their specialization.

Remove know from knowledge and you are standing on the ledge. When are we going to rescue ourselves from the ledge?
