﴿تُولِجُ ٱلَّيْلَ فِى ٱلنَّهَارِ وَتُولِجُ ٱلنَّهَارَ فِى ٱلَّيْلِ وَتُخْرِجُ ٱلْحَىَّ مِنَ ٱلْمَيِّتِ وَتُخْرِجُ ٱلْمَيِّتَ مِنَ ٱلْحَىِّ وَتَرْزُقُ مَن تَشَآءُ بِغَيْرِ حِسَابٍ﴾

You cause the night to enter the day, and You cause the day to enter the night; and You bring the living out of the dead, and You bring the dead out of the living. And You give provision to whom You will without account."

Surah Al-A'raf : 40 Meccan

﴿إِنَّ ٱلَّذِينَ كَذَّبُوا۟ بِـَٔايَٰتِنَا وَٱسْتَكْبَرُوا۟ عَنْهَا لَا تُفَتَّحُ لَهُمْ أَبْوَٰبُ ٱلسَّمَآءِ وَلَا يَدْخُلُونَ ٱلْجَنَّةَ حَتَّىٰ يَلِجَ ٱلْجَمَلُ فِى سَمِّ ٱلْخِيَاطِ وَكَذَٰلِكَ نَجْزِى ٱلْمُجْرِمِينَ﴾

Indeed, those who deny Our verses and are arrogant toward them - the gates of Heaven will not be opened for them, nor will they enter Paradise until a camel enters into the eye of a needle. And thus do We recompense the criminals.

Surah At-Tawba : 16 Medinan

﴿أَمْ حَسِبْتُمْ أَن تُتْرَكُوا۟ وَلَمَّا يَعْلَمِ ٱللَّهُ ٱلَّذِينَ جَٰهَدُوا۟ مِنكُمْ وَلَمْ يَتَّخِذُوا۟ مِن دُونِ ٱللَّهِ وَلَا رَسُولِهِۦ وَلَا ٱلْمُؤْمِنِينَ وَلِيجَةً وَٱللَّهُ خَبِيرٌۢ بِمَا تَعْمَلُونَ﴾

Do you think that you will be left [as you are] while Allah has not yet made evident those among you who strive [for His cause] and do not take other than Allah, His Messenger and the believers as intimates? And Allah is Acquainted with what you do.

Surah Al-Hajj : 61 Medinan

﴿ذَٰلِكَ بِأَنَّ ٱللَّهَ يُولِجُ ٱلَّيْلَ فِى ٱلنَّهَارِ وَيُولِجُ ٱلنَّهَارَ فِى ٱلَّيْلِ وَأَنَّ ٱللَّهَ سَمِيعٌۢ بَصِيرٌ﴾

That is because Allah causes the night to enter the day and causes the day to enter the night and because Allah is Hearing and Seeing.

Surah Luqman : 29 Meccan

﴿أَلَمْ تَرَ أَنَّ ٱللَّهَ يُولِجُ ٱلَّيْلَ فِى ٱلنَّهَارِ وَيُولِجُ ٱلنَّهَارَ فِى ٱلَّيْلِ وَسَخَّرَ ٱلشَّمْسَ وَٱلْقَمَرَ كُلٌّ يَجْرِىٓ إِلَىٰٓ أَجَلٍ مُّسَمًّى وَأَنَّ ٱللَّهَ بِمَا تَعْمَلُونَ خَبِيرٌ﴾

Do you not see that Allah causes the night to enter the day and causes the day to enter the night and has subjected the sun and the moon, each running [its course] for a specified term, and that Allah, with whatever you do, is Acquainted?

Surah Saba : 2 Meccan

﴿يَعْلَمُ مَا يَلِجُ فِى ٱلْأَرْضِ وَمَا يَخْرُجُ مِنْهَا وَمَا يَنزِلُ مِنَ ٱلسَّمَآءِ وَمَا يَعْرُجُ فِيهَا وَهُوَ ٱلرَّحِيمُ ٱلْغَفُورُ﴾

He knows what penetrates into the earth and what emerges from it and what descends from the heaven and what ascends therein. And He is the Merciful, the Forgiving.

Surah Fatir : 13 Meccan

﴿يُولِجُ ٱلَّيْلَ فِى ٱلنَّهَارِ وَيُولِجُ ٱلنَّهَارَ فِى ٱلَّيْلِ وَسَخَّرَ ٱلشَّمْسَ وَٱلْقَمَرَ كُلٌّ يَجْرِى لِأَجَلٍ مُّسَمًّى ذَٰلِكُمُ ٱللَّهُ رَبُّكُمْ لَهُ ٱلْمُلْكُ وَٱلَّذِينَ تَدْعُونَ مِن دُونِهِۦ مَا يَمْلِكُونَ مِن قِطْمِيرٍ﴾

He causes the night to enter the day, and He causes the day to enter the night and has subjected the sun and the moon - each running [its course] for a specified term. That is Allah, your Lord; to Him belongs sovereignty. And those whom you invoke other than Him do not possess [as much as] the membrane of a date seed.

Surah Al-Hadid : 4 Medinan

﴿هُوَ ٱلَّذِى خَلَقَ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضَ فِى سِتَّةِ أَيَّامٍ ثُمَّ ٱسْتَوَىٰ عَلَى ٱلْعَرْشِ يَعْلَمُ مَا يَلِجُ فِى ٱلْأَرْضِ وَمَا يَخْرُجُ مِنْهَا وَمَا يَنزِلُ مِنَ ٱلسَّمَآءِ وَمَا يَعْرُجُ فِيهَا وَهُوَ مَعَكُمْ أَيْنَ مَا كُنتُمْ وَٱللَّهُ بِمَا تَعْمَلُونَ بَصِيرٌ﴾

It is He who created the heavens and earth in six days and then established Himself above the Throne. He knows what penetrates into the earth and what emerges from it and what descends from the heaven and what ascends therein; and He is with you wherever you are. And Allah, of what you do, is Seeing.

Surah Al-Hadid : 6 Medinan

﴿يُولِجُ ٱلَّيْلَ فِى ٱلنَّهَارِ وَيُولِجُ ٱلنَّهَارَ فِى ٱلَّيْلِ وَهُوَ عَلِيمٌۢ بِذَاتِ ٱلصُّدُورِ﴾

He causes the night to enter the day and causes the day to enter the night, and he is Knowing of that within the breasts.
