البُرَاقُ

A certain beast which Mohammad rode on the night of the ascension [to heaven]; (S, Msb, * K;) or which the apostles ride in ascending to heaven; resembling a mule; (Msb;;) or less than the mule, but greater than the ass: (K:) so called because of the intense whiteness of his hue, and his great brightness; or because of the quickness of his motion; in respect of both of which he is likened to lightning.
