Allah reminds His servants of His favors towards them by subjugating for them
the night and day, without which they could not survive. He explains that if He
made the night continuous, lasting until the Day of Resurrection, that would be
harmful for them and would cause boredom and stress. So He says:
[مَنْ إِلَـهٌ غَيْرُ
اللَّهِ يَأْتِيكُمْ بِضِيَآءٍ]
(which god besides Allah could bring you light) meaning, `with which you
could see things and which would bring you relief'
[أَفَلاَ
تَسْمَعُونَ]
(Will you not then hear) Then Allah tells us that if He had made the day
continuous, lasting until the Day of Resurrection, that would also be harmful
for them and their bodies would get tired from so much movement and activity.
Allah says:
[مَنْ إِلَـهٌ غَيْرُ
اللَّهِ يَأْتِيكُمْ بِلَيْلٍ تَسْكُنُونَ فِيهِ]
(which god besides Allah could bring you night wherein you rest) meaning, `to
rest from your work and activity.'
[أَفلاَ
تُبْصِرُونَوَمِن رَّحْمَتِهِ]
(Will you not then see It is out of His mercy) towards you,
[جَعَلَ لَكُمُ
الَّيْلَ وَالنَّهَارَ]
(that He has made for you the night and the day) He created both,
[لِتَسْكُنُواْ
فِيهِ]
(that you may rest therein) during the night,
[وَلِتَبْتَغُواْ مِن
فَضْلِهِ]
(and that you may seek of His bounty) during the day, by traveling, moving
about and working.
[وَلَعَلَّكُمْ
تَشْكُرُونَ]
(and in order that you may be grateful.) So that you may give thanks to Allah
by performing all kinds of acts of worship at night and during the day. Whoever
misses something during the night can make it up during the day, and vice versa.
This is like the Ayah,
[وَهُوَ الَّذِى
جَعَلَ الَّيْلَ وَالنَّهَارَ خِلْفَةً لِّمَنْ أَرَادَ أَن يَذَّكَّرَ أَوْ
أَرَادَ شُكُوراً ]
(And He it is Who has put the night and the day in succession, for such who
desires to remember or desires to show his gratitude.) (25:62). And there are
many similar Ayat.
[وَيَوْمَ
يُنَـدِيهِمْ فَيَقُولُ أَيْنَ شُرَكَآئِىَ الَّذِينَ كُنتُمْ تَزْعُمُونَ
وَنَزَعْنَا مِن كُلِّ أُمَّةٍ شَهِيداً فَقُلْنَا هَاتُواْ بُرْهَـنَكُمْ
فَعَلِمُواْ أَنَّ الْحَقَّ لِلَّهِ وَضَلَّ عَنْهُمْ مَّا كَانُواْ يَفْتَرُونَ
]
(74. And the Day when He will call to them, and will say: "Where are My
(so-called) partners, whom you used to assert'') (75. And We shall take out from
every nation a witness, and We shall say: "Bring your proof.'' Then they shall
know that the truth is with Allah, and the lies which they invented will
disappear from them.)
