Just so you know, this Surat is giving the story about Moses praying to God and God's response to his prayer. It has nothing to do with Muhammad. Here is the full context of it:
And Moses chose seventy of his people for Our place of
meeting: when they were seized with violent quaking, he prayed:
"O my Lord! if it had been Thy will Thou couldst have destroyed,
long before, both them and me: wouldst Thou destroy us for the
deeds of the foolish ones among us? this is no more than Thy
trial: by it Thou causest whom Thou wilt to stray, and Thou
leadest whom Thou wilt into the right path. Thou art our
Protector: so forgive us and give us Thy mercy; for Thou art
the best of those who forgive.
[7:156] And ordain for us that which is good, in this life and
in the Hereafter: for we have turned unto Thee."
He said: "With My punishment I visit whom I will; but My mercy
extendeth to all things. That (mercy) I shall ordain for
those who do right, and practise regular charity, and
those who believe in Our signs;-
[7.157] those who follow the messenger, the unlettered Prophet,
whom they find mentioned in their own (scriptures),- in the law
and the Gospel;- for he commands them what is just and forbids
them what is evil; he allows them as lawful what is good (and
pure) and prohibits them from what is bad (and impure);
He releases them from their heavy burdens and from the yokes
that are upon them. So it is those who believe in him, honour
him, help him, and follow the light which is sent down with him,-
it is they who will prosper."
[7.158] Say: "O men! I am sent unto you all, as the Messenger of
Allah, to Whom belongeth the dominion of the heavens and the earth:
there is no god but He: it is He That giveth both life and death.
So believe in Allah and His Messenger, the Unlettered Prophet, who
believeth in Allah and His words: follow him that (so) ye may be
guided."
Bolded is the part the TC quoted for reference.
