Guardian Angels

S 13:11 He has mu’aqqibat in front of him and behind him who guard him from Allah’s command. Allah does not change what is with a people until they change what is with themselves. And when Allah has wanted evil with a people there is no cause for it and they have no governor instead of him.

The Jalalayn:

For him for man are attendants angels who follow him to his front and to his rear guarding him through God’s command that is by His command from the danger of the jinn and others. Indeed God does not alter the state of a people — He does not deprive them of His grace — unless they have altered the state of their souls from their comely nature through an act of disobedience. And if God wills misfortune chastisement for a people there is none that can repel it either from among the attendant angels or others; and they for whom God wills misfortune have no protector min wālin min is extra to avert it from them apart from Him that is other than God. https://www.altafsir.com/Tafasir.asp?tMadhNo=0&tTafsirNo=74&tSoraNo=13&tAyahNo=11&tDisplay=yes&UserProfile=0&LanguageId=2

Ibn Kathir:

(For him (each person), there are angels in succession, before and behind him. They guard him by the command of Allah.) Allah states that there are angels who take turns guarding each servant, some by night and some by day. These angels protect each person from harm and accidents. There are also angels who take turns recording the good and evil deeds, some angels do this by day and some by night. There are two angels, one to the right and one to the left of each person, recording the deeds. The angel to the right records the good deeds, while the angel to the left records the evil deeds. There are also two angels that guard and protect each person, one from the back and one from in front. Therefore, there are four angels that surround each person by day and they are replaced by four others at night, two scribes and two guards. https://quranx.com/Tafsir/Kathir/13.10

In S 5:67 regarding the founder of Islam: Messenger, send what has been sent down to you from your lord and if you have not done so then you have not sent his message. And Allah protects you from people. Allah does not guide the kafirun people.

It will be remembered that he was poisoned and supposedly bewitched.
