He was the Amir of Tablighi Jamaat from 1944 to 1965
HE HAS SAID
" that the Arabs must always take the leading role in Islamic advocacy, because they were the people chosen by Allah for this task as He revealed His final message in their language. Hence he was keen to spread his efforts and the Tableegh work to Arab countries.
He also realized that the best centers to spread this work were Makkah and Madinah, regularly visited by pilgrims from all over the Muslim world.
Therefore, he gave particular attention to educating Indian and Pakistani pilgrims, speaking to them at the ports of Bombay and Karachi, before embarking on their journey.
He would teach them the proper way of performing their pilgrimage rituals, and educate them in the need for Islamic advocacy.
Thus, he was able to form groups of advocates from the pilgrims.
These groups undertook the task of speaking to other pilgrims in the Grand Mosques in Makkah and Madinah.
This generated interest among pilgrims of other countries who approached al-Kandhlawi to send groups to their areas. He responded to their requests and the Tableegh work began to take roots in several Arab countries.
