Although the name "Israfel" does not appear in the Qur'an, mention is repeatedly made of an unnamed trumpet-angel assumed to identify this figure: "And the trumpet shall be blown, so all those that are in the heavens and all those that are in the earth shall swoon, except Allah; then it shall be blown again, then they shall stand up awaiting." —Qur'an (39.68).
In Islamic tradition he is said to have been sent, along with the other three Islamic archangels, to collect dust from the four corners of the earth, although only Izra'il succeeded in this mission. It was from this dust that Adam was formed.
Israfel holds his holy trumpet to his lips century after century, awaiting the signal from God to sound it at the Last Judgement. At this time he will descend to Earth and stand upon the holy rock in Jerusalem. The first blow of his trumpet will shatter the world, and the second blow will awaken the dead and summon them to judgement.
Certain sources indicate that, created at the beginning of time, Israfel possesses four wings, and is so tall as to be able to reach from the earth to the pillars of Heaven. A beautiful angel who is a master of music, Israfel sings praises to God in a thousand different languages, the breath of which is used to inject life into hosts of angels who add to the songs themselves.
Israfel has been associated with a number of other angelic names, including Uriel, Sarafiel and Raphael.
"The Islamic angel of music. It is said that he will sound the trumpet during the Last Judgement. He has four wings and is said to tower into the heavens. Thrice daily and nightly, he sheds enormous tears while watching humans tormented in Hell."
