Who Says 'Say!' ?

In a number of passages a sentence is introduced with the word 'Say!'. Whereas this is supposedly Allah giving a command as to what to say to its boss, there is no internal evidence that it is indeed Allah. Moreover, why are there passages in which he is directed to say such-and-such? Were those directions ONLY what he was to say to people?

A Messenger’s Speech?

The Anonymous Quran

Not directly related to this issue but which should be of interest to readers is S 21:4. The Hafs version of the Quran, along with a few others, says: "He said [Qala]: My lord knows the speech in the sky and the Earth. And he is the hearer, the learned." whereas the Warsh, along with other versions, has: "Say [Qul]: My lord knows the speech in the sky and the Earth. And he is the hearer, the learned." In the Warsh there is a command to say what comes after the verb. Obviously, despite what a Muslim will say, the meanings are different. Only one of the readings can be correct.
