Talking about 'Mashallah', Wajid Khan told a website, "Mashallah' is mashallah. We had composed the tune of the song and never thought it would feature in the film Ek Tha Tiger. We had once made Salman Khan listen to the tune and he quite liked it. Since we weren't composing for the film, we thought it would be unethical from our end to suggest the song for the film."
Wajid further added, "Once, when we were casually discussing the song with Salman bhai, who had by then forgotten the song, he was super excited. He gave us few suggestions and asked us to prepare for it. And later asked us to give a demo. After listening to 'Mashallah', Aditya Chopra asked us to give the song as it was."
No doubt, 'Mashallah' is one of the most melodious songs of Ek Tha Tiger!
