AL AN'AAM — Ayat 61

وَهُوَ الْقَاهِرُ فَوْقَ عِبَادِهِ وَيُرْسِلُ عَلَيْكُم حَفَظَةً حَتَّىَ إِذَا جَاء أَحَدَكُمُ الْمَوْتُ تَوَفَّتْهُ رُسُلُنَا وَهُمْ لاَ يُفَرِّطُونَ

And He is the subjugator over His servants, and He sends over you guardian-angels until, when death comes to one of you, Our messengers take him, and they do not fail [in their duties].
