Spiritual songs of A. R. Rahman

This is a long due post.  I had been contemplating writing this for many days, but the list of songs grew too much to accommodate in a single post.  I had also thought about writing a separate post about qawwalis of A. R. Rahman, mainly the trio:  Piya Haji Ali from Fiza, Khwaja Mere Khwaja from Jodha Akbar, and Kun Faya Kun from Rockstar.  I could not complete that project too.  Then, I wanted to dedicate a post to Mann Mohana from Jodha Akbar; again I couldn’t do it.  Finally, here I am with this post, and I have decided to base this post only on three songs, three different genres, three different religions, dedicated to that one Almighty.
