Belief in angels is one of the articles of faith, and the Quran describes this belief as an act of righteousness:
".........It is righteousness to believe in God and the Last Day and the angels and the book and the messengers... “(2:177).
Angels are special creatures of God whom the Quran describes as messengers because of the noblest task of communicating between God and His Holy Prophets (ï·º). The Quran says:
"He sends down His angels with inspiration of His command to such of His servants as he pleases......" (16:2).
Angels are made of light and are not visible to ordinary people. All the angels are the most obedient servants of God who always obey His command. Their submission to God can be judged by the fact that they even prostrated before Adam when commanded. Some of the angels have been mentioned in the Quran with names, and the details of their duties and functions are found in the Hadith literature. The Quran mentions Mikal (Mikaeel) who according to the Muslim faith is responsible for rainfall and distribution of 'rizq' (means of sustenance).
Israfil (not mentioned in the Quran) will blow the Trumpet
or Sur that will herald the onset of the Day of Judgment, and this is
repeatedly mentioned in the Quran. Izrael is the angel of death. Angel Jibril
(Gabriel) stands on top of all the angels and has been referred to as Ruh
(spirit), Ruh al Amin (the trustworthy spirit), and Ruh al Quds (the Holy
Spirit): Thus we can see that angels constitute an important part of the
spiritual aspect of Islam.
