﴿ وَهُوَ ٱلْقَاهِرُ فَوْقَ عِبَادِهِۦ ۖ وَيُرْسِلُ عَلَيْكُمْ حَفَظَةً حَتَّىٰٓ إِذَا جَآءَ أَحَدَكُمُ ٱلْمَوْتُ تَوَفَّتْهُ رُسُلُنَا وَهُمْ لَا يُفَرِّطُونَ ﴾

“And He alone holds sway over His servants. And He sends forth heavenly forces to watch over you until, when death approaches any of you, Our messengers cause him to die: and they do not overlook [anyone].”

(He is the Omnipotent) the All-Conquering (over His slaves. He sendeth guardians) angels: two angels during the day and two at night; they record your good and bad deeds (over you until, when death cometh unto one of you, Our messengers) i.e. the angel of death and his assistants (receive him, and they neglect not) they do not delay the time of death by even a fraction of a second.
