Hazrat Moulana Muhammad Ilyaas (rahmatullahi ‘alaih) once mentioned:
Our effort (of strengthening the imaan and yaqeen of people) aims towards strengthening the foundation of Deen. This movement of Da’wat and Tableegh is in reality a movement of reviving imaan in the hearts of people. In this day and age, many people who engage in collective efforts presume that the foundation of the imaan of the Ummah is strong. Therefore, they focus on developing and improving the secondary aspects of people’s Deen. However, we feel that the very first need of the Ummah is for the radiance of true imaan to illuminate their hearts (so that the secondary aspects can firmly take root). (Malfoozaat Hazrat Moulana Muhammad Ilyaas (rahmatullahi ‘alaih) pg. 61)
