Haizum
In Islamic tradition, Haizum (Arabic: حيزوم) is the horse of the archangel Gabriel. It is a white, flaming, spiritual horse that has wings like that of a pegasus and can fly swiftly from one cosmic plane to another in a second. Haizum was God's gift to Gabriel for pleasing Him.
A legend based on sura Ta-Ha, 96 relates that dust from Haizum’s hoofprints was thrown the golden calf’s mouth.
It is mentioned in Sahih Muslim that Abd Allah ibn Abbas said: "While on that day a Muslim from the Ansar was chasing a disbeliever, he heard over him the swashing of a whip and the voice of the rider saying: 'Go ahead Haizum.' He looked at the disbelievers who had fell on the ground on his back. The man came to Allah's Messenger (sallallahu alaihe wa-sallam) and related the incident, upon which Allah's Messenger (sallallahu alaihe wa-sallam) said: "You have told the truth. This was the help from the third Heaven."[1]
