This song has heavy Muslim undertones. The way this word is sung is reminiscent of Judas, another Lady Gaga song, that makes use of Christian themes and imagery. Compare Judas, Juda-a-a-a to Aura-a-a-a Aura-a-a-a.
In both songs, Gaga subverts preconceptions of religious ideas to convey a different message.
