Assalamoalaikum everyone

I live in a muslim majority society. But the problem is more than 80 percent of the people are not practicing here. Many of them go to the masjid only for the jumuah prayer. Many don't even go for that. Bad language, backbiting, violence is common here.

My question is what can we do for the betterment of our society? How to give dawah to these people? I know that the situation of Arabia before Muhammad(saw) was worse than this. So how did they give dawah?

There are many groups working for this cause. And they're doing great work. But, I just want to know your thoughts.

I feel like there's a responsibility on our shoulders. So I just thought asking you guys about it.
