However, soon after meeting Maulvi Ilyas Kandelvi, the founder of Tableeghi Jamaat, he left his job.

In one of his speech he narrated that he went to meet Maulvi Ilyas Kandelvi on the advice of Maulana Maudoodi.

Upon joining the Tableeghi Jamaat at an early stage of his life, he decided to spend his remaining life in Tableegh (Dawah) and was with Maulvi Ilyas till his death.

Haji Wahab migrated to Pakistan after 1947, along  with a few other colleagues and founded Madarssa Arabia in Raiwind junction Lahore.

He went on to visit every province and village of Pakistan for Tableegh.

The main focus of his first visit was to teach people Kalma and Namaz (prayer) at an early stage along with getting education, respecting humanity and spending life in Tableegh.

He has organised Tableeghi Ijtima (religious congregation) all over Pakistan and founded the Tableeghi Markaz in all big cities of the country.

At first the Jamaat comprised of a few Marakaz, but later it spread across the country.

This month two Ijtima held at Raiwind from November 2 to 13. About one million people participated in the gatherings, while thousands attended the it from across the globe.

It is expected that a crowd of a half-a-million will participate in his funeral prayer.
