How should insults to the Prophet Muhammad (PBUH) be handled?
What should we do when we discover people (deliberately or otherwise) insulting the noble prophet? Even on this board we've seen (non Muslim) members essentially call him a fake and a liar while on other sites they are even more vicious with the insults.
As Muslims, should we yet again ignore the provocations? and how far should we let them go? Is there any guidance in the holy Quran against those who attack us and our beliefs?
