Belief in the Angels
As we have indicated, when we have believed in the prophets and messengers, it becomes our duty to believe in everything they came to tell us, and when we have believed in the Divine Scriptures sent down upon the prophets and messengers, it also becomes our duty to believe in all the news they have brought.
Among this news brought by the prophets and messengers in the Holy Scriptures is: the angels.
It is obligatory upon us to believe in the angels in the form and manner described to us by the prophets and messengers, as revealed to them in the Holy Books sent down upon them.
Belief in the angels has details. We believe in the Angel Gabriel (Jibreel), Michael (Mika'eel), Israfeel, the Angel of Death, the Angel Guarding the Hellfire, and the like. All of these angels were clearly described by name by the prophets and messengers in the Holy Books sent down upon them.
Those we do not know by name we believe in generally—that they are slaves of Allah Almighty and that they are numerous.
It is imperative that we believe in all of the angels, and that we love them all, for they are servants of Allah Almighty who do His bidding. We do not hate them or bear animosity toward any of them. For whoever is an enemy to any of them (as the Jews did the Angel Gabriel, peace be upon him), he is an enemy of Allah (Mighty & Majestic), and he thereby becomes a disbeliever.
As the Almighty has said,
{"Whoever is an enemy to Allah, His Angels, His Messengers, Gabriel and Michael, then verily, Allah is an enemy to the disbelievers."}
[Al-Baqarah 2: 98]
We should know that the angels have powers and abilities unlike human beings. They are among the signs of Allah (Mighty & Majestic). Belief in them is from belief in Allah (Glorious & Exalted) and His Great Power (Noble & Sublime).
