The Book of Pilgrimage (Kitab Al-Hajj)
Muslim :: Book 7 : Hadith 3207
Abu Humaid (Allah be pleased with him) reported: We went out along with Allah's Messenger (may peace be upon him) in the expedition of Tabuk, and Humaid further related: We proceeded until we reached the valley of Qura; and Allah's Messenger (may peace be upon him) said: I am going forth, so he who among you wants to move fast with me may do so; and he who likes to go slowly may do so. We proceeded until Medina wag within our sight. and he said: This is Tibba (another name of Medina) ; this is Ubud, the mountain which loves us and we love it.
