Has there been scholarly discussion of the significance (or subtlety) of the ayahs beginning with "Say"? For example:
Say: He is Allah, the One! (112:1)
All praise is due to Allah, the Lord of the Worlds. (1:2)
(There is nothing special about these choices of examples other than they came to my mind at the time of writing.)
The analyses I am seeking are, in what ways would the meaning of the above ayahs would be different if there was no "Say" in the first example, and the second example started with "Say"?
