Giving da’wah is in general a communal obligation. But practically in our times, one can argue that in many cases it becomes an individual fard that we’re all required to practice. This is because there are so few Muslims who have any correct knowledge of the religion, and so many who’re giving improper da’wah, teaching people innovations in religion and often shirk. In order to combat the da’wah of shaytan, we need to build the habit of calling people to Allah.
