Tabligh By A Common Man
As a principle , we common muslims in our individual capacity are only responsible for our immediate social circle and after that, if we get time and resources, we can choose to do dawah in other circles as well. And this obligatory dawah is regarding the obvious matters of religion and the ones which fall under maruf , munkar etc. Please also refer to the video below from 39:43 to 43:44 https://youtu.be/a7nEMTUNPJc?t=2383
