The Messenger as Conveyor of Revelation

So, consider how He, Glorified be He, attributed the word to the Messenger using 'say',

and attributed it to His Own speech in His saying: 'Until he hears the words of Allah',

For the Messenger says to the one to whom he is sent what he was commanded to say,

so he says: 'I said such and such',

and I said to him what you commanded me to say to him,

as the Messiah said: 'I said nothing to them except what You commanded me with',

and the one who sends says to the messenger: 'Say to them such and such',

as He, Exalted be He, said: 'Say to My servants who have believed to establish prayer',

'Say to My servants to speak that which is best',

'Say to the believers to lower their gaze', and similar passages.

Therefore, when the Messenger conveyed this, it is correct to say: 'The Messenger said such', and this is the Messenger's word,

meaning: he said it as a conveyer, and this is his word communicated from his Sender.

And it is not fitting in any of that to say: 'He spoke to them with such and such',

Nor did the Messenger speak with such and such,

Nor is it with the words of a noble Messenger, nor in any single instance.

Rather, it was said to the Truthful One as he recited a verse: 'Is this your word and the word of your companion?'
