So I swear by whatsoever you see,

And by whatsoever you see not,

That this is verily the word of an honoured Messenger [i.e. Jibrael (Gabriel) or Muhammad ﷺ which he has brought from Allah].

It is not the word of a poet, little is that you believe!

Nor is it the word of a soothsayer (or a foreteller), little is that you remember!

This is the Revelation sent down from the Lord of the 'Alamin (mankind, jinns and all that exists).

And if he (Muhammad ﷺ) had forged a false saying concerning Us (Allah),

We surely should have seized him by his right hand (or with power and might),

And then certainly should have cut off his life artery (Aorta),

And none of you could withhold Us from (punishing) him.

And verily, this Quran is a Reminder for the Muttaqun (pious - see V. 2:2).

And verily, We know that there are some among you that belie (this Quran). [Tafsir At-Tabari, Vol. 29, Page 68]

And indeed it (this Quran) will be an anguish for the disbelievers (on the Day of Resurrection).

And Verily, it (this Quran) is an absolute truth with certainty.

So glorify the Name of your Lord, the Most Great.
