Angel hierarchy

There is no standard hierarchical organization in Islam that parallels the 
division into different "choirs" or spheres,
 as hypothesized and drafted by early medieval Christian theologians.
 Most [who?] Islamic scholars agree that this is an unimportant topic in Islam,
 especially since such a topic has never been directly mentioned or addressed in the Qur'an.
 However, it is clear that there is a set order or hierarchy that exists between Angels,
 defined by the assigned jobs and various tasks to which angels are commanded by God.

 The Angel Jibreel is the most recognized angel, as in Islam this angel delivers
 the message of Allah (Quran) to the prophets.

Some scholars suggest that Islamic angels can be grouped into fourteen categories
. Numbers 2-5 are considered archangels.

Hamalat al-'Arsh, Those who carry the 'Arsh (throne of God) (40:7)

Gabriel, the angel of revelation, who is said to be the greatest of the angels.

Raphael, who will blow the trumpet twice at the end of time.
 At the first blow, everyone in heaven and earth will die including all angels

 (e.g., Azrael, Gabriel and Raphael himself)

 and at the second blow, all will be brought forth to meet their Lord.

Michael (2:98), who provides nourishments for bodies and souls.

Azrael, the angel of death.
The angels of the seven heavens.

Hafaza (The Guardian Angel):

Kiraman Katibin (Honourable Recorders) (Al Infithaar 82:11),
 two of whom are charged with each human being; one writes down
 good deeds, and the other writes down evil deeds.

Mu'aqqibat (The Protectors) (Ar-Raad 13:10-11), who keep people from death
 until its decreed time and who bring down blessings.

Nakir and Munkar, who question the dead in their graves.

Darda'il (The Journeyers), who travel in the earth searching out assemblies
 where people remember God’s name.[2]

Harut and Marut are believed to be two angels who came down to Babylon.
 The knowledge gained from these angels was misused by the evil ones
 in teaching sorcery to the inhabitants there.(2:102) .

The angels charged with each existent thing, maintaining order
 and warding off corruption. Their number is known only to God.[3]
