What is the basis for the Tabligh jamaat's Ijtimas?

Answer

The basis for the Ijtimas is the very same as the basis for the establishment of the Madaaris. It is to bring people together for mass ta'leem of the original teachings of the Deen and to form groups to go to places to impart the Sunnah. This was the original objective. However, nowadays the Ijtima has outlived its utility just as the Madaaris jalsahs are no longer Islamically productive. On the contrary, jalsahs and the Ijtimas have become merrymaking gatherings of riya, takabbur, bigotry and israaf. They are not only redundant. They are now spiritually ruinous.
