How many angels are involved in the death of every human? Or does Allah do everything or nothing? Let’s see from Muhammad’s Koran:
Angels

Indeed, those whom the angels take [in death] while wronging themselves – [the angels] will say, “In what [condition] were you?”
They will say, “We were oppressed in the land.”
The angels will say, “Was not the earth of Allah spacious [enough] for you to emigrate therein?”
For those, their refuge is Hell – and evil it is as a destination.
Koran 4:97
And who is more unjust than one who invents a lie about Allah or says, “It has been inspired to me,”
while nothing has been inspired to him, and one who says, “I will reveal [something] like what Allah revealed.”
And if you could but see when the wrongdoers are in the overwhelming pangs of death while the angels extend their hands, [saying], “Discharge your souls! Today you will be awarded the punishment of [extreme] humiliation for what you used to say against Allah other than the truth and [that] you were, toward His verses, being arrogant.”
Koran 6:93
Then how [will it be] when the angels take them in death, striking their faces and their backs?
Koran 47:27
Guardian Angels

6:60 And it is He who takes your souls by night and knows what you have committed by day. Then He revives you therein that a specified term may be fulfilled. Then to Him will be your return; then He will inform you about what you used to do.
61 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].
62 Then they His servants are returned to Allah, their true Lord. Unquestionably, His is the judgement, and He is the swiftest of accountants.
Koran 6:60-62
Angel of Death

Say, “The angel of death who has been entrusted with you will take you. Then to your Lord you will be returned.”
Koran 32:11
I’m not sure if this passage is about the Angel of Death as “death” or if it’s Allah.
23:99 [For such is the state of the disbelievers] until, when death comes to one of them, he says, “My Lord, send me back 100 That I might do righteousness in that which I left behind.”
No!
It is only a word he is saying; and behind them is a barrier until the Day they are resurrected.
Koran 23:99-100
Of course, nothing happens as no one speaks while dead, as they are, you know, dead.
Allah

Allah takes the souls at the time of their death, and those that do not die [He takes] during their sleep.
Then He keeps those for which He has decreed death and releases the others for a specified term.
Indeed in that are signs for a people who give thought.
Koran 39:42
Malik

And they will call, “O Mālik, let your Lord put an end to us!”
He will say, “Indeed, you will remain.”
Koran 43:76
Conclusion

Muhammad’s incoherence with angels, guardian angels, an angel or Allah shows that none of these imaginary beings are involved with the deaths of all humans.
Muhammad was a false prophet, for a false god, Allah, for a false religion, Islam, without even a false book, the Koran.
