Foster Hindu parents bring up Farzana in Islamic tradition

[takeiteasy]

I wonder how Muslims tolerated a Hindu couple adopted a Muslim girl. common sense tells Muslims generally are furious in this regard. they see a Hindu family adopting a Muslim means converting one among them to other religion. that is the common mentality.
however, I remember a movie made in 60s with this theme

The film tells the story of a Hindu man who adopts a Muslim child and allows her to follow Muslim traditions.
