It is very recommended in Islam to start everything with the name of Allah. So starting the letters, books or presentations with name of Allah is very common. But it has been a question for me that is it suitable for the Muslims leaving in non-Muslim countries to use the name of Allah or God in public?
For example consider a student who wants to write a letter, or make a seminar in his/her department. Is it suitable that s/he use the name of Allah above the letter or presentation? Does it make negative or positive effect on the audiences?
Specially for the case that the major audiences are non Muslims or even people with no religion. Referenced answers are more than welcome.
