Tafsir Ibn Kathir -> Surah Al-A'raf -> The Day and the Night are among the Signs of Allah

Allah said,

﴿يُغْشِى الَّيْلَ النَّهَارَ يَطْلُبُهُ حَثِيثًا﴾

(He brings the night as a cover over the day, seeking it rapidly,) meaning, the darkness goes away with the light, and the light goes away with the darkness. Each of them seeks the other rapidly, and does not come late, for when this vanishes, the other comes, and vice versa. Allah also said;

﴿وَءَايَةٌ لَّهُمُ الَّيْلُ نَسْلَخُ مِنْهُ النَّهَارَ فَإِذَا هُم مُّظْلِمُونَ - وَالشَّمْسُ تَجْرِى لِمُسْتَقَرٍّ لَّهَـا ذَلِكَ تَقْدِيرُ الْعَزِيزِ الْعَلِيمِ - وَالْقَمَرَ قَدَّرْنَـهُ مَنَازِلَ حَتَّى عَادَ كَالعُرجُونِ الْقَدِيمِ - لاَ الشَّمْسُ يَنبَغِى لَهَآ أَن تدْرِكَ القَمَرَ وَلاَ الَّيْلُ سَابِقُ النَّهَارِ وَكُلٌّ فِى فَلَكٍ يَسْبَحُونَ ﴾

(And a sign for them is the night. We withdraw therefrom the day, and behold, they are in darkness. And the sun runs on its fixed course for a term (appointed). That is the decree of the All-Mighty, the All-Knowing. And the moon, We have measured for it mansions (to traverse) till it returns like the old dried curved date stalk. It is not for the sun to overtake the moon, nor does the night outstrip the day. They all float, each in an orbit.) ﴿36:37-40﴾ Allah's statement,

﴿وَلاَ الَّيْلُ سَابِقُ النَّهَارِ﴾

(Nor does the night outstrip the day) ﴿36:40﴾ means, the night follows the day in succession and does not come later or earlier than it should be. This is why Allah said here,

﴿يَطْلُبُهُ حَثِيثًا وَالشَّمْسَ وَالْقَمَرَ وَالنُّجُومَ مُسَخَّرَتٍ بِأَمْرِهِ﴾

(seeking it rapidly, and (He created) the sun, the moon, the stars subjected to His command.) meaning, all are under His command, will and dominion. Allah alerted us afterwards,

﴿أَلاَ لَهُ الْخَلْقُ وَالاٌّمْرُ﴾

(Surely, His is the creation and commandment) the dominion and the decision. Allah said next,

﴿تَبَارَكَ اللَّهُ رَبُّ الْعَـلَمِينَ﴾

(Blessed is Allah, the Lord of the all that exists!) which is similar to the Ayah,

﴿تَبَارَكَ الَّذِى جَعَلَ فِى السَّمَآءِ بُرُوجاً﴾

(Blessed be He Who has placed in the heaven big stars) ﴿25:61﴾ Abu Ad-Darda' said a supplication, that was also attributed to the Prophet ,

«اللَّهُمَّ لَكَ الْمُلْكُ كُلُّـهُ وَلَكَ الْحَمْدُ كُلُّهُ وَإِلَيْكَ يُرْجَعُ الْأَمْرُ كُلُّهُ، أَسْأَلُكَ مِنَ الْخَيْرِ كُلِّهِ وَأَعُوذُ بِكَ مِنَ الشَّرِّ كُلِّه»

(O Allah! Yours is all the kingdom, all the praise, and Yours is the ownership of all affairs. I ask You for all types of good and seek refuge with You from all types of evil.)

﴿ادْعُواْ رَبَّكُمْ تَضَرُّعًا وَخُفْيَةً إِنَّهُ لاَ يُحِبُّ الْمُعْتَدِينَ - وَلاَ تُفْسِدُواْ فِى الاٌّرْضِ بَعْدَ إِصْلَـحِهَا وَادْعُوهُ خَوْفًا وَطَمَعًا إِنَّ رَحْمَتَ اللَّهِ قَرِيبٌ مِّنَ الْمُحْسِنِينَ ﴾

(55. Invoke your Lord Tadarru`an and Khufyah. He likes not the aggressors.) (56. And do not do mischief on the earth, after it has been set in order, and invoke Him with fear and hope. Surely, Allah's mercy is (ever) near unto the good-doers.)
