The numbers of daily prayers “Salat” mentioned in the “Quran” are as follows:
1- Salat Fajr (صَلَاةِ الْفَجْرِ) (Dawn Prayer), (Sura Al-Nur 24:58) and (Sura Al-Isra 17:78)
2-Salat Isha’a (صَلَاةِ الْعِشَاءِ) (Dusk Prayer), (Sura Al-Nur 24:58) and (Sura Al-Isra 17:78)
3-Night Salat (17:79, 73:2, 73:20)
The following three “Salat” which are not mentioned in “Quran” by their names are as:
1- Salat Dhuhr (ظهر).
2- Salat Asr (عصر).
3- Salat Maghrib (مغرب).
Although, the words “Dhuhr (ظهر)”, “Asr (عصر)” and “Maghrib (مغرب)” are used in Quran but not as a “Term” defining “Salat”. In Sura Al-Nur 24: 58, the word “noon” is used but not as a “Salat Time” or as a “Salat Al-Dhuhr” but rather than as a “Time of Privacy/Rest Time”.
SALAT AND GLORIFICATION (TASBEEH) ARE TWO DIFFERENT THINGS.
24:41 Do you not see that everything in the heavens and the earth glorifies Allah? Even the birds in formation, each knows its SALAT AND ITS GLORIFICATION. And Allah is fully aware of everything they do.
The verse 30:17, 20:130, 50:39 are mentioning the timing of Tasbeeh ( Glorification) not Salat.
Salat means to Contact/Reach out/Remain attached/Follow closely.
Glorification can be performed after Sujjud. 50/40
50:40 And from the night glorify Him, and after Sujjud.
If glorification is Salat then why we have to perform it after Sujjud?
