Angels are mentioned many times in the Qur'an and ahadith (prophetic sayings).
Unlike humans, angels are described as not possessing free will, but are assigned different duties. Two of the most prominent angels mentioned by name in the Qur'an are Gabriel (Jibril) and Michael (Mikhail). Gabriel is the angel of revelation and Michael is the angel of compassion.
Other angels are referenced including those who are the scribes noting everything you do, the angel who will blow the horn to signal the end of the universe and commencement of the day of judgement and the angels who will question you in the grave.
