حَتَّىٰ إِذَا جَاءَ أَحَدَكُمُ الْمَوْتُ تَوَفَّتْهُ رُسُلُنَا وَهُمْ لَا يُفَرِّطُونَ
When death comes to one of you, Our messengers take that person's soul, and they do not fail in their duty. (Al-An'am 6:61)
A group of angels is appointed alongside the Angel of Death to take souls. The plural word rusuluna, 'Our messengers', reflects this assignment. All fulfill the task by Allah's command.
