Islam is about inviting people to Allah. And doing so without let up.
Just like Prophet Muhammad, Sallallahu Alaihi wa Sallam, did all his life.
If they don't listen to you in Makkah, go to Taif.
If they beat you up in Taif, move to Madinah.
Don't stop till you die.
That is how Islam -- and Prophet Muhammad, Sallallahu Alaihi wa Sallam -- changed the whole world in about 20 years or so.
