Hadrat Abu Ayyub Ansari (RA) reports that a desert Arab came to the Holy Prophet (SAW) and submitted: "O Prophet of Allah, I am very fond of horses. Will there be horses in heaven?" The Holy Prophet observed: "If you were sent to Paradise, you would be given a horse made of emerald. The horse will have two wings. You would mount the horse and it would fly you to where ever it might be your pleasure to go." Source: Tirmidhi.

This horse will be an aircraft in Heaven. The worldly aircraft is designed like a fish, whereas the heavenly aircraft will be in the form of a horse. The worldly aircraft is made of aluminum; the heavenly aeroplane will be made of emerald! (Comments from "Spectacle of Death").
