It is narrated from Hazrat Anas (may Allah be pleased with him) that once when the Prophet (peace and blessings be upon him) saw the Uhud mountain, he said: "We love this mountain and it loves us. O Allah! Hazrat Ibrahim (peace be upon him) declared Makkah as a sanctuary, and I declare the area between the two boundaries of Madinah as a sanctuary."
