Working with Oscar-winner AR Rahman, against whom a fatwa has been issued over “Muhammad: The Messenger Of God”, was a learning experience for Canadian multi-lingual singer Natalie Di Luccio, who has sung an Arabic track in the film. Apparently, Natalie, who had earlier worked with Rahman in S. Shankar’s film “I”, says, “I sang for his new film called ‘Muhammad…’. The film has gone to film festivals and hasn’t released in India yet. It’s a big budget Iranian film and I had Arabic songs, so he helped me a lot.”, says Natalie.
