The permissibility of depictions of Muhammad in Islam has been a contentious issue. Oral and written descriptions of Muhammad are readily accepted by all traditions of Islam, but there is disagreement about visual depictions. The Quran does not explicitly or implicitly forbid images of Muhammad. The ahadith present an ambiguous picture, but there are a few that have explicitly prohibited Muslims from creating visual depictions of human figures. It is agreed on all sides that there is no authentic visual tradition as to the appearance of Muhammad, although there are early legends of portraits of him, and written physical descriptions whose authenticity is often accepted.

A halo (from Ancient Greek ἅλως  'threshing floor, disk'; also called a nimbus, aureole, glory, or gloriole is a crown of light rays, circle or disk of light that surrounds a person in works of art. The halo occurs in the iconography of many religions to indicate holy or sacred figures, and has at various periods also been used in images of rulers and heroes. In the religious art of Ancient Greece, Ancient Rome, Christianity, Hinduism, and Buddhism, sacred persons may be depicted with a halo in the form of a circular glow, or flames in Asian art, around the head or around the whole body—this last form is often called a mandorla. Halos may be shown as almost any colour or combination of colours, but are most often depicted as golden, yellow or white or as red.
