۞ وَقَالَ ٱلَّذِينَ لَا يَرْجُونَ لِقَآءَنَا لَوْلَآ أُنزِلَ عَلَيْنَا ٱلْمَلَٰٓئِكَةُ أَوْ نَرَىٰ رَبَّنَا ۗ لَقَدِ ٱسْتَكْبَرُوا۟ فِىٓ أَنفُسِهِمْ وَعَتَوْ عُتُوًّۭا كَبِيرًۭا
And those who look not for a meeting with Us say: Why are angels not sent down unto us and (Why) do we not see our Lord! Assuredly they think too highly of themselves and are scornful with great pride.
Surah Al-Furqaan(25:21)

Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
The Statement of Allah the Exalted: "...And glorify the praises of your Lord, before the rising of the sun and before (its) setting (i.e., the Fajr, Ẓuhr and 'Aṣr prayers) ." (V.50:39)
Narrated Jarir bin `Abdullah:
We were in the company of the Prophet (ﷺ) on a fourteenth night (of the lunar month), and he looked at the (full) moon and said, "You will see your Lord as you see this moon, and you will have no trouble in looking at Him. So, whoever can, should not miss the offering of prayers before sunrise (Fajr prayer) and before sunset (`Asr prayer)." Then the Prophet (ﷺ) recited: 'And celebrate the praises of your Lord before the rising of the sun and before (its) setting.' (50.39)
