512. About Mohammed's spirits, how they are instructed and become angels

Spirits who approach Mohammed perform similar gyres as the angels, and indeed, along with singing in melodious voices, which I have heard for many days as I awoke from sleep. So they had been performing their own spiritual gyres throughout the night. Twice, and now once more, they were also allowed to enact singing displays, like the angels, one in fact concerning the Savior of the World, which they are said to have performed with a skill comparable to that of the angels, even so well that they were admitted into angelic choirs.
