Abbad bin Tamim narrates from his paternal uncle (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Ibrahim (peace be upon him) made Makkah sacred, and I have made Madinah sacred just as Ibrahim (peace be upon him) made Makkah sacred, and I have prayed for blessing in its mudd and its sa' just as Ibrahim (peace be upon him) prayed for Makkah."
