Unlike Russia, India and UAE have strong economic ties. Considering the Emirates imported ~30 Billion dollars worth of goods from India last year, it's quite clear what they can use the rupees for.
If your currency is not universal, then you have to produce stuff that people wants. India may not necessarily export enough to Russia for them to justify holding so much rupees.
UAE may actually be a decent fit because of the Indian labor it imports.
A lot of Dirhams are converted to Rupees as laborers send the money back to India, so this could help reduce costs for the workers, companies and the UAE.
