The composer, who has already won a Golden Globe [ Images ] and two Academy awards, registered wins in both the categories he was nominated for.
He was the earliest winner in the Best Compilation Soundtrack for a motion picture category and picked up another trophy for his song Jai Ho in the Best Motion Picture song category moments later.
"This is insane, God great again," the 44-year-old composer said while accepting the golden gramophones.
Rahman beat Steve Jordan for Cadillac Records, Quentin Tarantino [ Images ] for Inglourious Basterds [ Images ], the producers of Twilight and True Blood to bag the award in the best compilation soundtrack for a motion picture category.
In the Best Song category, Rahman's rivals included Bruce Springsteen for his song The Wrestler, from the Oscar-nominated movie of the same name.
Rahman's Grammy win was similar to his triumph at the Oscars [ Images ] last year where he picked up the Best Original Score statuette before winning the Oscar for Jai Ho, which has become an international anthem.
This is Rahman's first Grammy.
