Tablighi Jamaat call is simple that every muslim know
For this any Muslim can remind himself and all other Muslims.
4.They always STRESS that the participants who are non alim/not an scholar
are to speak within 6 qualities,( IMAN,SALAT, ILM O ZIKR.IKRAM E MUSLIM,IKHLAS E NIYAT,DAWAT E ILLALLAH) which they learn in ta'leem, and the 6-quality discussion.
