In The Name of Allah, The Merciful, The Bextower of Mercy.

Allah, The Most High, said:

قُلۡ أَرَءَيۡتُمۡ إِن جَعَلَ ٱللَّهُ عَلَيۡڪُمُ ٱلَّيۡلَ سَرۡمَدًا إِلَىٰ يَوۡمِ ٱلۡقِيَـٰمَةِ مَنۡ إِلَـٰهٌ غَيۡرُ ٱللَّهِ يَأۡتِيڪُم بِضِيَآءٍ‌ۖ أَفَلَا تَسۡمَعُونَ
قُلۡ أَرَءَيۡتُمۡ إِن جَعَلَ ٱللَّهُ عَلَيۡڪُمُ ٱلنَّہَارَ سَرۡمَدًا إِلَىٰ يَوۡمِ ٱلۡقِيَـٰمَةِ مَنۡ إِلَـٰهٌ غَيۡرُ ٱللَّهِ يَأۡتِيڪُم بِلَيۡلٍ۬ تَسۡكُنُونَ فِيهِ‌ۖ أَفَلَا تُبۡصِرُونَ
وَمِن رَّحۡمَتِهِۦ جَعَلَ لَكُمُ ٱلَّيۡلَ وَٱلنَّهَارَ لِتَسۡكُنُواْ فِيهِ وَلِتَبۡتَغُواْ مِن فَضۡلِهِۦ وَلَعَلَّكُمۡ تَشۡكُرُونَ

Say (O Muhammad ): “Tell me! If Allah made night continuous for you till the Day of Resurrection, who is an ilah (a god) besides Allah who could bring you light? Will you not then hear?” Say (O Muhammad ): “Tell me! If Allah made day continuous for you till the Day of Resurrection, who is an ilah (a god) besides Allah who could bring you night wherein you rest? Will you not then see?” It is out of His Mercy that He has put for you night and day, that you may rest therein (i.e. during the night) and that you may seek of His Bounty (i.e. during the day), and in order that you may be grateful. [Al-Qasas. 71-73]

The (night and day) are a bestowal from Allah to His servants and this should make them thankful, worship Allah alone and fulfil His Rights. Allah- out of His Mercy- created the day for them in order that they may seek after His Bounties- seeking after their provisions and livelihoods during daylight. And Allah created the night for them (as a means of) rest and repose- (allowing) their bodies and souls to take a rest due to tiredness after work during the day. This is a bounty of Allah (bestowed) on His servants and Mercy (from Him). Is there anyone who is able to do this (besides Allah)?

Regarding the night, He said: [أَفَلَا تَسْمَعُونَ -Then will you not then hear], and regarding the day, He said: [أَفَلَا تُبْصِرُونَ – Then will you not then see?]

This is because the (faculty) of hearing is sharper than the (faculty) of sight during night time, and the (faculty) of sight is sharper than the (faculty) of hearing during day time.

In these verses (i.e. Al-Qasas 71, 72 & 73) the servant is exhorted to ponder upon the blessings Allah has bestowed. He should contemplate what the situation would have been if such blessings were absent, because if a servant were to contemplate on the situation due to the presence of such blessings compared to what the situation would have been if such blessings were absent, he will realise the station of this favour, contrary to the one who merely goes along with the normal state of affairs and considers (these favours) as something that will neither cease nor come to an end. So his heart is hindered from praising Allah for these blessings and from realising that he is in need of Allah every time. This neither prompts his thoughts towards thanksgiving nor remembrance. [1]

Al-Hasan Al-Basri, may Allah have mercy upon him, said:

”The night and the day have not ceased to lessen the life spans and bringing close the appointed times of death.” [2]

Awn Bin Abdillah, may Allah have mercy upon him, said:

Indeed, the most beneficial days the believer has in the worldly life, is the one about which he thought he would not reach its end. [3]
