Minor Pilgrammage (Umra)
Bukhari :: Book 3 :: Volume 27 :: Hadith 28
Narrated Humaid:
Anas said, "Whenever Allah's Apostle returned from a journey, he, on seeing the high places of Medina, would make his she-camel proceed faster; and if it were another animal, even then he used to make it proceed faster."
Narrated Humaid that the Prophet used to make it proceed faster out of his love for Medina.
