"It is not only Indian culture.It is Prophet Muhammed Musthafa's (Saw) culture" Muhammad(P.B.U.H.) told that;
“ Two groups amongst My Ummah would be such, to whom Allah has freed from fire; One group would attack India & the Second would be that who would accompany Isa Ibn-e-Maryam(A.S.)”. (There is no options suddenly convert to islam)

Abu Hurairah Narrated that the Messenger of Allah said:
"I have been commanded to fight the people until they say La ilaha illallah (there is none worthy of worship except Allah). Whoever says it, his life and his property are safe from me, except for its right, and his reckoning will be with Allah." (Sahih)
