http://shabdkosh.raftaar.in/Meaning-of-मुसल्लम-in-English
So, for God the absolute the term 'perfect' is a chosen one. मौला refers to the Lord. So, it means Perfect Lord.
But, this is the literal meaning.
The sentence reads: यह तो हमारा मुसल्लम मौला है।
So, using It for यह तो, the contextual meaning is It is the essence of our being. This 'It' being used here is something very important,hence compared with Perfect God.
