There no other islam teaching inside mosque to the society.
All teaching about doing bad deeds intentionly is haram,fix by serious repent,and back the right to whom get oppressed.
Teaching doing good deeds to the people is what God wants, even by smile or remove a rock from road.
In general here big cities low religious displine, especially where poor cities,they much violence
Here same in mild of Sahara touristic area poor religious people.
I can say 0 violence.
Because they religious displine is their way of life.
