If one does not fear the authorities than Allah should suffice
There are many options besides violence
Legal or public help
There is always more regret than enjoyment after violence
If a moment of maddness leads to imprisonment than most crimanls regret their actions
When the family of the oppressed curses you the guilt is refreshed
Every enemy has family who rely on them just like us
What are the sins and consequences for gang violence?
Hurting a fellow muslim
Causing fear and troubling the neighbours and community
Disturbing a peaceful neighbourhood
Disrespecting elders in the community who have always explained the importance of good conduct
Putting your own family at risk
Presenting Islam and Muslims negatively
Setting a bad example for others
