Al-An'am 6:61

Wahuwa alqahiru fawqa AAibadihiwayursilu AAalaykum hafathatan hattaitha jaa ahadakumu almawtu tawaffat-hurusuluna wahum la yufarritoon

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 [i.e., angels of death] take him, and they do not fail [in their duties].

He is Dominant over His slaves, and He sends guardians over you until when death comes upon one of you, Our deputies take his soul in full, and they neglect nothing (from their duties).
