Question: It has been mentioned that [the name of] the Angel of Death is ‘Izraa.eel. So is this correct or not?
Response: It is not correct to call him ‘Izraa.eel, rather, it is said: Angel of Death, just as Allaah ‘Azza wa Jall has said:
…and it has not been authentically reported from the Prophet (sal-Allaahu ‘alayhi wa sallam) that his name is ‘Izraa.eel.
