what are the methods of dawa of christians in mauritius and how it is affecting the muslim?

Answer 1

my brother, there are 3 ways of teaching(making dawa) the nonmuslins:
1. if he/she is totaly nonmuslim i.e he/she doesnt have no any knowldge about islam, what you have to do is preaching (explaining) to him/her all Islam and debate him with a the way(hikma).  
2. if he/ she has some hint(knowledge) about Islam but need to know Islam more, give him/her all informations that he needs to know.
3.but if he/she knows all about Islam but intentionally tell hem/her to return to the right road, Islam and go away from him/her.
