From Sahih Bukhari (Hadith 1802):
Narrated Humaid:Anas said, "Whenever Allah's Messenger (ﷺ) 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 (ﷺ) used to make it proceed faster out of his love for Medina. Narrated Anas: As above, but mentioned "the walls of Medina" instead of "the high places of Medina." Al-Harith bin `Umar agrees with Anas
