Sayyiduna Anas (may Allah be pleased with him) said that when the Messenger of Allah (peace and blessings be upon him) came back from a journey and saw the walls of Madinah, he would make his she-camel go faster, and if it was another animal, he would urge it on.
(b) Isma'il bin Ja'far narrates from Humayd: Out of love for Madinah.
