A question answered by Shaikh Muhammad Salih Al-Munajjid regarding: “ There is a hadith, whoever sees a wrong must stop it by hand, etc and another: leave alone what does not concern you. would you clarify what to stop and what to leave alone. if i c someone doing immoral things in Saudi Arabia, like dating, etc. do i go and tell them not to while i know they probably wont listen, or do i just report it to some authority?”
