How should Muslims believe in the angels?

Muslims must believe in the blessed angels and know that they are God’s creation. Muslims believe in the existence of angels, and they believe in what is related in the shari’ah concerning their names, like Jibril [Gabriel]: Say (O Muhammad, to mankind): Who is an enemy to Gabriel! For he it is who has revealed (this Scripture) to your heart by God’s leave, confirming that which was (revealed) before it, and a guidance and glad tidings to believers; Who is an enemy to God, and His angels and His messengers, and Gabriel and Michael! Then, lo! God (Himself) is an enemy to the disbelievers [2:97-98]. And He said to the wives of the Prophet who rebelled against him, If you two turn unto God repentant, (you have cause to do so) for your hearts desired (the ban); and if you aid one another against him (Muhammad) then lo! God, even He, is his Protecting Friend, and Gabriel and the righteous among the believers; and furthermore the angels are his helpers [66:4]. And our Lord mentioned the Angel of Death in the Qur’an saying, Say: The angel of death, who has charge concerning you, will gather you, and afterward unto your Lord you will be returned [32:11]. And our Lord mentioned the gatekeeper of the Hellfire and mentioned his name, which is Malik, And they cry: O master! Let your Lord make an end of us. He says: Lo! here you must remain [43:77]. And He mentioned the angels of the Hellfire saying, Ah, what will convey unto you what that burning is! - It leaves naught; it spares naught. It shrivels the man. Above it are nineteen. We have appointed only angels to be wardens of the Fire, and their number have We made to be a stumbling-block for those who disbelieve; that those to whom the Scripture has been given may have certainty, and that believers may increase in faith; and that those to whom the Scripture has been given and believers may not doubt; and that those in whose hearts there is disease, and disbelievers, may say: What does God mean by this similitude ? Thus God sends astray whom He will, and whom He will He guides. None knowes the hosts of thy Lord save Him. This is naught else than a Reminder unto mortals [74:27-31].
There are different orders of angels that have been mentioned in the authentic prophetic tradition that are not mentioned in the Quran and must be believed in as well. Examples of these are the angle of mercy and the blower of spirits. The Prophet said, “Your creation comes together in your mother’s womb in forty days. Then it is a clot for a similar period. Then it is a lump of flesh for a similar period. God sends an angel to it to blow into it the spirit and to command four things: its sustenance, its life span, its deeds, and whether it will have good or bad destiny. I swear by He other than Whom there is no divinity, one of you may do the works of the people of Paradise until there is but an arm’s length between them, then destiny will catch up with him and he will end with the works of the people of Hell and enter it. And a man may do the works of the people of Hell until there is but an arm’s length between them, then destiny will catch up with him and he will end with the works of the people of Paradise and enter it.”

Angels must be believed in in general, and particularly those about whom God has taught us and particularly those that God has made known in detail as has been mentioned in the preceding texts and others. Belief in the angels has a tremendous effect on the believer’s being elevated to reach his Lord; feeling the existence of blessed creatures around him makes him constantly shy away from disobedience. And our final prayer is “All praise is due to God, Lord of the Worlds.”
