Explanation

Belief in angels is one of six articles of faith. Angels created from light, without free will – they only obey Allah. Each has specific duties assigned by Allah.

Major angels: Jibril (Gabriel – revelation), Mikail (provision and nature), Israfil (will blow trumpet for Day of Judgment), Azrael (death), Munkar and Nakir (question in grave), Kiraman Katibin (record deeds).

Angels differ from jinn (created from fire, have free will) and humans (created from clay, have free will). Angels surround believers, attend prayer gatherings, and seek forgiveness for believers.
