Musnad Ahmad 329:17

'Affan narrated to us, he said: Wuhayb narrated to us, he said: 'Amr ibn Yahya narrated to us, from 'Abbad ibn Tamim, from 'Abdullah ibn Zayd, from the Messenger of Allah, may Allah bless him and grant him peace, that he said: "Indeed, Ibrahim made Makkah sacred and prayed for it, and I have made Al-Madinah sacred just as Ibrahim made Makkah sacred. And I have prayed for them in their mudd and their sa' just as Ibrahim prayed for Makkah."
