Hazrat Shaikh Moulana Muhammad Zakariyya (rahmatullahi ‘alaih) once mentioned the following:
It is my experience that any work which is commenced with ikhlaas (sincerity and according to the sunnah), despite taking place on a small scale, gains momentum and progresses swiftly. On the contrary, any work that commences with show and publicity, it does not take root nor does it continue. I have observed this in many efforts and movements.
Daarul Uloom Deoband commenced with just a single student and ustaad under a tree in the Chatta Musjid, and Madrasah Mazaahirul Uloom commenced in Chowki Musjid with a single ustaad and two students. The work of da’wat and tableegh also commenced with ikhlaas on a small scale, yet today, it has spread throughout the entire world like the rainfall that reaches every land and causes grass and vegetation to grow.
