ISLAM: THE RELIGION OF UNIVERSAL HARMONY

Where does it says to fight peope of other religion. when you dont know something its better to shut your mouth then sounding stupid.
Arjuna was fighting his own cousins(own caste/clan). when mahabharta was written there was no other religion.
Secondly what krishna means is to fight what is right and to protect the citizens. where it says to kill non hindus/muslims???

all world knows about is muslim terrorists and u can go and make a case for hindus but sadly noone gonna listen you.
