This is the 10th verse of Ghalib’s 21st ghazal.
Use kon dekh sakta ke, ygana hai voh yakta
Who could sight him; he is sole and matchless
jo dui ki boo bhi hoti to kahin do-char hota
If there were slightest possibility of being more than one like him, we would have spotted
gana=sole, unique; yakta= matchless; do-char hota=we would have sighted him
Meaning: In this verse, Ghalib expresses his views about what is God. In Quran at several places there are mentions about singularity of God. Ghalib says, God has no similarity with anything, he is unique, he has no parallel; that is why no one can see him. If he had even an element of plurality, he would have been visible somewhere.
Aasi’s opinion: Quran says if heavenly or mundanely there were more than one God, it would have definitely created conflict among them; because, by nature more than one power will allow peace. If two or more Gods fight to finish, only one will be victorious if he is to be called omnipotent; those who are overpowered cannot be God.
