Sahih Muslim Book 7, Hadith Number 3157.

Chapter : Eminence of Medina, Allah’s Apostle (may peace be upon him) showered blessings upon it. Its sacredness and unlawfulness of hunting and lopping of trees and demarcation its precincts.

Anas b. Malik (Allah be pleased with him) reported that Allah’s Messenger (may peace be upon him) said to Abu Talha (Allah be pleased with him): Find for me a servant from amongst your boys to serve me. Abu Talha went out along with me and made me sit behind him. And I used to serve Allah’s Messenger (may peace be upon him) whenever he got down from the camel. And in one Hadith he said: He proceeded and when (the mountain of) Uhud was within sight, he said: This is the mountain which loves us and we love it. And as he came close to Medina he said: O Allah, I declare (the area) between the two mountains of it (Medina) sacred just as Ibrahim declared Mecca as sacred. O Allah, bless them (the people of Medina) in their mudd and sa’.
