Benefits of the Verse ((And when your Lord said to the angels...)): Affirming that speech belongs to Allah and that it is with letters and sound.

In this noble verse, it is affirmed that speech belongs to Allah (Mighty and Majestic) This is the position of the righteous Salaf: that we believe that Allah the Exalted has speech with which He speaks.
And it is affirmed that His speech is with letters and sound. From where did we take that it is with letters? From His saying: And the phrase: is the content of the speech, and it consists of letters And we take that it is with sound from the fact that He said to the angels, meaning a speech that reached the angels. It is not possible for His speech to reach the angels unless it is with what? Unless it is with sound, and it is so. Then the sound may be faint or strong, as He the Exalted said: This is the position of the people of the Sunnah, and the truth is that it is the ultimate perfection for Allah (Mighty and Majestic). Indeed, it is among the greatest attributes of perfection that Allah (Mighty and Majestic) speaks with what He wills, in creation and in legislation. So everything that happens in the universe exists by His word. The evidence is And everything is intended by Allah, so everything is by divine decree. As for the legislative speech, it is what Allah revealed to the messengers.
