Before sleep the Prophet ﷺ taught reciting Ayat al-Kursi and the last three surahs (Al-Ikhlas, Al-Falaq, An-Nas). The Qur'an reminds us that sleep itself is Allah taking the soul and returning it — a nightly trust placed in His hands.
ٱللَّهُ يَتَوَفَّى ٱلْأَنفُسَ حِينَ مَوْتِهَا وَٱلَّتِى لَمْ تَمُتْ فِى مَنَامِهَا ۖ فَيُمْسِكُ ٱلَّتِى قَضَىٰ عَلَيْهَا ٱلْمَوْتَ وَيُرْسِلُ ٱلْأُخْرَىٰٓ إِلَىٰٓ أَجَلٍۢ مُّسَمًّى ۚ إِنَّ فِى ذَٰلِكَ لَءَايَٰتٍۢ لِّقَوْمٍۢ يَتَفَكَّرُونَAllaahu yatawaffal anfusa heena mawtihaa wallatee lam tamut fee manaamihaa fa yumsikul latee qadaa 'alaihal mawta wa yursilul ukhraaa ilaaa ajalim musammaa; inna fee zaalika la Aayaatil liqawmai yatafakkarron“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.”Qur'an 39:42 · Surah Az-Zumar (Saheeh International)
The cited verse frames sleep as a lesser death — Allah takes the souls at night and returns them by day — which is why the Prophet ﷺ taught adhkar for entrusting yourself to Allah before sleep.
