What does the Quran say about sleep?

Rest as a mercy

Sleep is given, not merely suffered. The night is described as a covering and sleep as a cutting off, a repose.

• An-Naba 78:9✦ skyread

  وَجَعَلْنَا نَوْمَكُمْ سُبَاتًا

  And made your sleep [a means for] rest

• Al-Furqaan 25:47✦ skyread

  وَهُوَ ٱلَّذِى جَعَلَ لَكُمُ ٱلَّيْلَ لِبَاسًا وَٱلنَّوْمَ سُبَاتًا وَجَعَلَ ٱلنَّهَارَ نُشُورًا

  And it is He who has made the night for you as clothing and sleep [a means for] rest and has made the day a resurrection.

• Ar-Room 30:23✦ skyread

  وَمِنْ ءَايَٰتِهِۦ مَنَامُكُم بِٱلَّيْلِ وَٱلنَّهَارِ وَٱبْتِغَآؤُكُم مِّن فَضْلِهِۦٓ إِنَّ فِى ذَٰلِكَ لَءَايَٰتٍ لِّقَوْمٍ يَسْمَعُونَ

  And of His signs is your sleep by night and day and your seeking of His bounty. Indeed in that are signs for a people who listen.

The nightly death

Souls are described as taken in sleep and sent back until an appointed term: the same verb used for dying.

• Az-Zumar 39:42✦ skyread

  ٱللَّهُ يَتَوَفَّى ٱلْأَنفُسَ حِينَ مَوْتِهَا وَٱلَّتِى لَمْ تَمُتْ فِى مَنَامِهَا فَيُمْسِكُ ٱلَّتِى قَضَىٰ عَلَيْهَا ٱلْمَوْتَ وَيُرْسِلُ ٱلْأُخْرَىٰٓ إِلَىٰٓ أَجَلٍ مُّسَمًّى إِنَّ فِى ذَٰلِكَ لَءَايَٰتٍ لِّقَوْمٍ يَتَفَكَّرُونَ

  Allah takes the souls at the time of their death, and those that do not die [He takes] during their sleep. Then He keeps those for which He has decreed death and releases the others for a specified term. Indeed in that are signs for a people who give thought.

• Al-An'aam 6:60✦ skyread

  وَهُوَ ٱلَّذِى يَتَوَفَّىٰكُم بِٱلَّيْلِ وَيَعْلَمُ مَا جَرَحْتُم بِٱلنَّهَارِ ثُمَّ يَبْعَثُكُمْ فِيهِ لِيُقْضَىٰٓ أَجَلٌ مُّسَمًّى ثُمَّ إِلَيْهِ مَرْجِعُكُمْ ثُمَّ يُنَبِّئُكُم بِمَا كُنتُمْ تَعْمَلُونَ

  And it is He who takes your souls by night and knows what you have committed by day. Then He revives you therein that a specified term may be fulfilled. Then to Him will be your return; then He will inform you about what you used to do.

Dreams that mean something

Yusuf's sura is the book's long argument that a dream can carry knowledge, and that reading one is a gift.

• Yusuf 12:4✦ skyread

  إِذْ قَالَ يُوسُفُ لِأَبِيهِ يَٰٓأَبَتِ إِنِّى رَأَيْتُ أَحَدَ عَشَرَ كَوْكَبًا وَٱلشَّمْسَ وَٱلْقَمَرَ رَأَيْتُهُمْ لِى سَٰجِدِينَ

  [Of these stories mention] when Joseph said to his father, "O my father, indeed I have seen [in a dream] eleven stars and the sun and the moon; I saw them prostrating to me."

• Yusuf 12:100✦ skyread

  وَرَفَعَ أَبَوَيْهِ عَلَى ٱلْعَرْشِ وَخَرُّوا۟ لَهُۥ سُجَّدًا وَقَالَ يَٰٓأَبَتِ هَٰذَا تَأْوِيلُ رُءْيَٰىَ مِن قَبْلُ قَدْ جَعَلَهَا رَبِّى حَقًّا وَقَدْ أَحْسَنَ بِىٓ إِذْ أَخْرَجَنِى مِنَ ٱلسِّجْنِ وَجَآءَ بِكُم مِّنَ ٱلْبَدْوِ مِنۢ بَعْدِ أَن نَّزَغَ ٱلشَّيْطَٰنُ بَيْنِى وَبَيْنَ إِخْوَتِىٓ إِنَّ رَبِّى لَطِيفٌ لِّمَا يَشَآءُ إِنَّهُۥ هُوَ ٱلْعَلِيمُ ٱلْحَكِيمُ

  And he raised his parents upon the throne, and they bowed to him in prostration. And he said, "O my father, this is the explanation of my vision of before. My Lord has made it reality. And He was certainly good to me when He took me out of prison and brought you [here] from bedouin life after Satan had induced [estrangement] between me and my brothers. Indeed, my Lord is Subtle in what He wills. Indeed, it is He who is the Knowing, the Wise.

Where it falls

Every verse on this subject, placed across the book in reading order. This subject leans Meccan, the earlier and more urgent material.
