the night so that we can also be included amongst the righteous bondmen of Allah عَزَّوَجَلَّ, because performing worship during the night is a very beautiful attribute of righteous bondmen of Allah عَزَّوَجَلَّ. Allah عَزَّوَجَلَّ has stated this attribute in Ayah 64 of Surah Al-Furqan, part 19 like this:

وَ الَّذِیْنَ یَبِیْتُوْنَ لِرَبِّهِمْ سُجَّدًا وَّ قِیَامًا(۶۴)

Translation from Kanz-ul-Iman: And who spend the night prostrating and standing, for their Lord. (Part 19, Surah Al-Furqan, Ayah 64)

Similarly, in Ayah 16 of Surah As-Sajdah, part 21 Allah عَزَّوَجَلَّ has stated:

تَتَجَافٰى جُنُوْبُهُمْ عَنِ الْمَضَاجِعِ یَدْعُوْنَ رَبَّهُمْ خَوْفًا وَّ طَمَعًا٘-وَّ مِمَّا رَزَقْنٰهُمْ یُنْفِقُوْنَ(۱۶)

Translation from Kanz-ul-Iman: Their sides stay detached from their beds and they pray to their Lord with fear and hope - and they spend from what We have bestowed upon them. (Part 21, Surah As-Sajdah, Ayah 16)

Likewise, in Ayah 17 and 18 of Surah Az-Zariyaat part 26 Allah عَزَّوَجَلَّ has stated:

كَانُوْا قَلِیْلًا مِّنَ الَّیْلِ مَا یَهْجَعُوْنَ(۱۷)وَ بِالْاَسْحَارِ هُمْ یَسْتَغْفِرُوْنَ(۱۸)

Translation from Kanz-ul-Iman: They used to sleep only a little during the night. And used to seek forgiveness before dawn.

(Part 26, Surah Az-Zariyaat, Ayah 17-18)

Dear Islamic brothers! In the above-mentioned blessed Ayahs the strong desire of the righteous bondmen to worship Allah عَزَّوَجَلَّ has been mentioned by saying that when people sleep these righteous personages become occupied with the worship of their Lord.
