This looks like a Bollywood production.. Indian rather than Arabic?
I am ignorent of the distinction. My Hindu as well as my arabic language skills are rather poor. All I really can say is HIN = people, dus = the river, hence Hindus are the people of the Indus Vally river system.
(Dus, note the vast majority of the river systems in central and eastern Europe start with Din,Danube, Dinepter,(look at the map) - it was Ancient Persian Dinn for water, or river.)
I am giving a poor account of this but a quick look at the map will show what I mean.
