512. CONCERNING THE SPIRITS OF MAHOMED; HOW THEY ARE INSTRUCTED SO THAT THEY MAY BECOME ANGELS The spirits who go to Mahomed perform similar gyres as the angels, and indeed with song or with a melodious voice, which I have heard for many days when I have awakened from sleep; so that they performed their spiritual gyres through the whole night. On two occasions, and again now, it has been granted them also to form melodious representations like the angels, and indeed concerning the Savior of the world. They are said to have done this with such dexterity that they equaled the angels; so they also are admitted into angelic choirs.
