وَهُوَ ٱلْقَاهِرُ فَوْقَ عِبَادِهِۦ ۖ وَيُرْسِلُ عَلَيْكُمْ حَفَظَةً حَتَّىٰٓ إِذَا جَآءَ أَحَدَكُمُ ٱلْمَوْتُ تَوَفَّتْهُ رُسُلُنَا وَهُمْ لَا يُفَرِّطُونَ ۝٦١

6:61 He is the Omnipotent over His slaves. He sendeth guardians over you until, when death cometh unto one of you, Our messengers receive him, and they neglect not.
