And this section of the surahs

resembles their beginning,

the beginning of documents and treaties

where they say:

"This is what so-and-so and so-and-so made peace upon"

"This is what so-and-so enjoined."

And the Prophet - peace be upon him - wrote in the treaty of Al-Hudaybiyah

"This is what Muhammad decreed" - peace be upon him -.

And some of them began by mentioning the sender and the receiver,

as the Most High - said -:

- {The revelation of the Book is from Allah, the Almighty, the Wise}

- {A Book whose verses are perfected then detailed from One Wise, Acquainted}

And this section resembles the decrees in which is written

"This is what was issued from the Sublime Porte"

or "a notice issued from the presence of the Caliphate to the residents of such-and-such city."

And the Prophet - peace be upon him - wrote:

"From Muhammad the Messenger of Allah to Heraclius the great of the Romans."

And some surahs began in the manner of brief letters and addresses without a title and introduction,

like His saying - the Most High -:

- {When the hypocrites come to you, they say, "We testify that indeed you are the Messenger of Allah"}
