Da'wat wa Tabligh ka kaam waseela hai.
Asal Kaam Sunnat aur Shariat par chalna hai.
Jaise wudu' waseela hai namaaz ka.
Mawlana Ibrahim Devla (db).
Translation:
The work of Da'wah & Tabligh is a means.
The real work is to practice the Sunnah & follow the Shariah.
In the same way that Wudu'(minor ablution) is a means for offering Salah.
Wa salam.
