Manipulation of 25:64 in order to instate a non Quranic Salat

And those who prostrate and stand before their Lord during the night.
25:64
One of the prayers observed by a large number of Muslims is called "Salat Qiyam A-Layl" (The rising of the night prayer). There is no mention in the Quran of such a Salat. The only prayers named in the Quran and authorised by God are three:
1- Salat Al-Fajr (Dawn Prayer), 24:58
2- The Wusta Salat (Middle Prayer) 2:238
3- Salat Al-Isha (Evening Prayer), 24:58

Some preachers, in their attempt to instate various prayers that have no mention in the Quran have sadly resorted to manipulating a number of Quranic verses and twisting their meaning to imply that they refer to such non-Quranic prayers. One of these verses is 25:64.

Please also refer to the following verses which have been similarly manipulated with the same aim of justifying a number of prayers that are not authorised by God in the Quran:

- Manipulation of 20:130
- Manipulation of 30:17-18
- Manipulation of 17:79

The claim is that the acts of prostrating and standing mentioned in 25:64 refer to the Salat, and therefore the words
"during the night" refer to an additional Salat on top of the Salat named in the Quran.

The Analysis

1-
First stop in our analysis is the claim of a 'Salat on top of the Salat named in the Quran'.
These words present a marked contradiction with God's assurance that the Quran has all the details and that nothing has been left out of the Book:

Shall I seek other than God as a lawmaker when it is He who has brought down to you the Book fully detailed?
6:114

This (Quran)
is not a fabricated hadith, but an authentication of what came before it, a detailed account of all things and guidance and mercy for people who believe. 12:111

We did not leave anything out of the Book; then to their Lord they will be summoned. 6:38

We brought the Book down to you providing explanations for all things, guidance, mercy, and good news for the Submitters.
16:89

It follows that to imply that God mentioned some Salat by name in the Quran and also left out the names of other lawful Salat, is to openly declare rejection of the Quranic verses above which confirm that all the details are in the Quran, and that nothing has been left out.
This is a case of doublethink, which is the act of simultaneously accepting two mutually contradictory beliefs as correct.

2-
The words "prostrate and stand before their Lord" are indeed acts observed during the Salat. The words in 25:64 speak of a Salat (or more) that is observed "during the night."
To establish which Salat does this verse speak about, we need to first ascertain the Quranic definitions of the 'Day' and the 'Night'; when do they start and when do they end.
The Day (Nahar) starts as soon as the sun rises, and it ends as soon as the sun sets.
The Night (Layl) starts when the sun sets and ends as soon as the sun rises.
For the Quranic details, please see: When does the Night begin?

3- Based on the Quranic definition of the 'Night', it follows that the 2 Salat: Fajr and Isha, are both observed "during the night."
The Fajr Salat is observed before the sun rises, thus it is observed during the night.
Similarly, the Isha Salat is observed after the sun sets, thus the Isha Salat is also observed during the night.

The words in 25:64 do not refer to any Salat that was never mentioned in the Quran. The words in this verse refer to the lawful Salat which God decreed to be observed
"during the night." Those are the 2 Quranic Salat, Fajr and Isha.
