Hazrat Moulana Muhammad Ilyaas (rahmatullahi ‘alaih) once mentioned:
In this work of Da’wat and Tableegh (inviting people towards deen), in order for one to see the desired level of progress, one is required to inculcate within himself sincerity in all his works and actions. Apart from the need to inculcate sincerity, there is a vital need for one to do the work with mashwarah (i.e. consulting the seniors of the work and not taking any independent decision). Without making mashwarah with the seniors, there is a fear that great harm could take place. (Malfoozaat Hazrat Moulana Muhammad Ilyaas (rahmatullahi ‘alaih) pg.114)
