In our opinion, the root malady and sickness of the ummah in this day and age is that their hearts are void of the enthusiasm and value of deen. If the concern and yearning for deen is created in them, and the importance and respect of deen is revived in their hearts, then you would see complete deen coming alive in their lives. The primary purpose of the effort of da’wat and tableegh is to make an effort to create the enthusiasm and value of deen in people’s hearts. Through the enthusiasm being created, they will be motivated to go to the ‘Ulamaa and learn and practice deen correctly. The purpose of this effort is not to just teach people to recite the kalimah and correct their salaah, etc.
