You know these people aint even worth the bother. The best we can do is keep promoting the good teachings of our beloved phrophet (peace and blessing be upon him) Bro iam sure you have read Surah Yaseen.......know what i mean. Some people are just impossible to talk to.
Salaam,
Without even trying you say they are a bothersome people.
We muslim perform dakwah and defend the faith and the Prophet.
In no way can we allow other to malign our Propeht.
If a group or a people were to ridicule in the presence of a muslim,if the muslim remain silent,then they will say,....SEE EVEN THEY ARE NOT GETTING ANGRY OVER THEIR PROPHET.
So i say again,...
Making excuses to practise the faith is easy enough
To not make excuses and to do it is difficult.
As the saying goes,any fool cna make a baby,only a MAN can raise one.
So walk away ,walk away...make excuses..
It will become easier as time goes,as the non muslim excalete the mockery of the Prophet...just walk away.
They say the first step is the hardest...but it already sets the path..
